The Catalogue Quarterly Reports, complement to the 1998 Catalogue of Joint Stamp Issues (Volume 1 to 15) published on a quarterly basis between 1999 and 2001, (these leaflets were never available on line beforeand are reproduced here in color, whenever possible)
The Quarterly Reports (Volume 16 to 39), only in English, improvement of the Complement, published between 2002 and 2006
The 2006 Catalogue of Joint issues (English) – 500 samples were printed (a few remain availableif interested)
The Catalogue Supplements published on a yearly basis between 2007 and 2022 (English) until the 2022 Catalogue became available on line
The pages of information from the first web site (http://www.philarz.net) that were filed in the News Archives. These pages were updated regularly between 2010 and 2020 (English) and archived in Quarterly pages.
From 2022 on, the new catalogue became available, associated to this new web pages and blog. In total, this new section provides access to additional 3,300+ archive pages. The interest is mainly to get access to the history of the creation of some joint issues, to some monographs, to some specific articles and to some images in particular first day cancellations or non-approved joint issues. Of course, this is also the first time that the 2006 catalogue is on line.
In parallel, another chapter was opened providing access to a maximum of dedicated articles that were published over the past 30 years. The list is obviously not complete, but additions are welcome. The articles are provided as pdf copies and in their original language (no translation is provided at this stage). So far, 22 articles have been posted representing 83 published pages to read. The list does not include the stamp description leaflets (notices, leaflets, press releases, …) issued by individual postal administrations.
It is time to clean the catalogue and to amend it with the information collected over the Summer. Unfortunately, a quite large number of announced issues did not (yet) materialize. From the ones listed so far, one can consider that the following issues have failed or were wrongly attributed a joint character:
The 150th anniversary of the relationship between Japan and Peru translated in a miniature sheet with 10 different stamps issued on August 21, 2023 by Japan and a pair of se-tenant stamps from Peru, supposed to be released by end of October 2023. The bilateral treaty was signed on August 21, 1873. In absence of common date of issue, common design and no announcement of collaboration for the creation of these stamps, they cannot be considered as joint. This is simply a set of stamps celebrating the same event without joint character (information provided by Kenneth Sequeira, Singapore).
The expected French – Poland 100th anniversary of Polish immigration to France stamps were limited to the French stamp issued on September 4, 2023. No link with Poland was created at this occasion.
Additional information posted 20230929: Poland issued on September 29, 2023, a stamp related to this topic, with a different design, and Polish postal administration confirmed this is not to be considered as joint.
We are still waiting for information regarding the following issues, but there is a great doubt that they will really materialize:
No news from the India Vietnam ‘Fighting Sports’ joint issue originally to be released on April 23, 2023. Actually, the Vietnamese stamps were released on that date, but rapidly retrieved from sale after about 4,000 samples went on the market. No information is available from the Indian side.
No news from this other Vietnam stamps supposed to become a joint issue with Uruguay. The Uruguay souvenir sheet was released on April 27, 2023
Morocco and Oman did not issue a common stamp in May 2023 as previously announced
No news from the India Mauritius joint issue supposed to be released on August 25, 2023
The few joint issues that became available at post offices are reported in the catalogue. The catalogue was updated with all this information and the information is available in Vol XV – V07. Additional information introduced in the catalogue include the following:
In the T20230509 PostEurop series, the Nagorno Karabagh stamps are also described as non-perforated (Information provided by Kay Sorensen, Germany). We are still missing information from Albania and apparently Armenia will not participate this year (to be confirmed).
SEPAC stamps are not anymore joint issues (only the topic is common) but all stamps, mint, are presented in a yearly folder that is described in Vol I – V06, chapter “Folders and Booklets”
Eventually Ali Ahmed Med Achour (Algeria) signaled an error on the Algerian stamp from the T20230902 PAPU series. Within the stamp, the Arabic words refer to the town of Arusha and do not mention the PAPU tower. The complete Arabic text should look like the one printed on the Moroccan or the Egyptian stamps (see illustrations below). On the margin of the sheet, there is also a single Arabic word next to the English title, that simply means “inauguration”.
A year has been completed again. There is now little chance that a last minute 2022 joint issue is discovered and therefore the chapter 2022 in the catalogue can be closed as well. Information, images, and quotation have been updated for this full year.
Unfortunately, there are still missing information from some countries from which joint partners were expected. The Iran-Kenya stamps showing coffee beans and safran flower stamps and dedicated to the 50th anniversary of the establishment of Iran-Kenya diplomatic relations remain as a unilateral souvenir sheet issue from Iran on June 24, 2022. No information about Kenyan stamps issued during the year 2022 has been published. The situation is identical for the Iran – Serbia souvenir sheet (85 years of diplomatic relations, September 30, 2022) for which information about the Iranian stamps is missing. These unilateral issues have been removed from the catalogue, but in the case someone finds the missing information, here are the pictures of the issued stamps as a reminder.
The India-Vietnam and India – Thailand joint issues respectively announced by Vietnam and Thailand in their 2022 philatelic programs did not come to a finalized product. These joint issues may be rescheduled in 2023 but had to be removed from the catalogue as well.
Altogether, this allowed a complete update of the catalogue becoming now the 2023 edition V4.0 and all the 15 parts have been modified (mainly shift of pages) with minor improvement in each of the part.
At the same time, this work gave us the opportunity to provide some statistics about the joint issue season 2022. In terms of figures, the year 2022 translates in the following: there are 51 entries reported in the catalogue for the year 2022, but among which only 40 are true joint issues: 1 Se-tenant [S] but no Unique [U], 27 Twin (same design, same date of issue) [T], 7 Concerted (same design, different date of issue) and 5 Parallel [P] (same date of issue, different designs) issues. Additionally, we reported 2 Omnibus series [O], 2 Territorial issues [D] and 1 issue with Borrowed design [B]. For the year 2022, the catalogue provides 225 illustrations, describes 344 items together with 675 quotations.
Another interesting point relates to involved countries. As many as 66 countries participated at least to one true joint issue, but the winner is surprisingly Mexico with 7 participations. Mexico is followed by Russia (5 times, almost exclusively with Asian eastern countries) and by the group Argentina, Egypt, Georgia, Oman and Vatican which were involved 4 times each. This high participation of Oman and Georgia are also quite a surprise. Eventually Armenia, Belarus, Israel, Poland, Tunisia and the UAE were involved 3 times each. There are no new first comer in this 2022 list, but it is interesting to notice the come back of countries such as Cambodia, North Korea or Tanzania. This year also saw the issue of the first joint crypto stamps between Austria and the Netherlands.
The new version of thecatalogue in 15 volumesdescribes over 1,750 pages, 2,150 stamp issues among which more than 1,500 are true joint issues, and provides more than 8,100 illustrations. 32,900+ quotations are linked to more than 14,800 different items.
Note also that from now on, and in order to reduce the amount of intermediate versions in thearchive files, only the first edition of each year will be kept accessible. Numbering of intermediate version will continue to be used, but at the beginning of each year the versions with small modifications will be erased. The first version of each year will play the role of reference for earlier catalogue versions. Edition 2023 intiates the publication of V4.0.
To complete this exercice, it becomes also interesting to show the evolution of the production of Joint issues over the past years. On the basis of the catalogue entries, it became possible to create the following graph which shows the number of joint issues released each year since 1960. The blue curve gives the evolution of the number of Twin issues [T], the orange curve the combined Parallel [P] and Concerted [C] issues and the grey curve the total [T]+[P]+[C] including also the rare Unique [U] and Se-tenant [S] issues. Omnibus [O], Territorial [D] and Borrowed design [B] issues are not included in this graph. The peak release was reached in 2019, just before the Corona pandemic, with 53 true joint issues in one year, but the graph shows also an apparent plateau of around 40 issues per year that stays since 2007. Over this 15 years period, the number of products for a single country, and in particular by-products such as souvenir sheets, miniature sheets and even stationery, did continue to increase (not shown on the graph). A peak production of items above 500 was reached during the years 2016 and 2019, while the average figures since 2007 over this period was maintained around 280 (with severe variations during the Covid period, 230 in 2020, 140 in 2019 and back to 340 in 2022).
At this time it is difficult to predict the progression for the next years, but a stabilization around 40-45 issues per year would make sense. Continue enjoying collecting joint issues and have a nice year 2023.
A large update of the catalogue took place by end of October 2022, adding more than 10 pages to the Volume 15. The updated version of Catalogue 2022 Vol 15 V3.11 is now on line with new information for issues to be released in November and December 2022, but also a new list for issues expected during the year 2023. Major catalogue information affect the Tiger Forum series and the World Post Day issue with now 21 countries involved. Very recently, Argentina, Colombia and Mexico were added, but this list is still not complete. On page 1720 a non-approved ActNow – Stop the war series is described as well. The first list of countries participating to the common design stamp issue to be released at the occasion of the Arab League Summit is provided on page 1744. The other countries (up to a possible total of 22 countries possible) are expected to release their stamps by November 1-2, 2022.
The country and topic indexes of Volume 1 V3.06 have been updated accordingly.
In June 2022, the online stamp-selling company Delcampe issued the second volume of its Magazine (Delkcampe Magazine 2). If you take a look at this newspaper, you will find on pages 13-15 an article dedicated to joint stamp issues, with pictures taken from their sales’ web site, which refers to philarz.com and our on-line catalogue. Thanks a lot Delcampe.
The new web site (this one: https:philarz.com) including the Joint Stamp Issue full catalogue is now in place since half a year, but some collectors are still loocking for information in the previous web site (http://philarz.net/, which is still open, but will be completely shut down by mid of next year). This page is intended to reassure collectors that all the data available in the previous web site can be accessed in these pages. This information is just available in a different place and in a different form. To facilitate your search, here are some hints how to better explore and benefit from this web site and the appended catalogue. In fact, the largest part of the information is now embedded in the on-line catalogue. This page addresses most of the FAQ received over the past months:
Where is the page providing the explanations of the definitions of the different joint issues?
Definition of joint issues are all described on the web page ‘FAQ‘, but in full details directly in Volume 1 of the on-line catalogue, more precisely from pages 11 to 24, which are updated when necessary. It is recommended to explore also the other pages of this catalogue Volume 1 which over 100 pages gives all introduction information and definitions
Where is the upcoming issues section?
The upcoming issues section does exist, but in a different form. In fact all new information that will in the future be translated in an official joint issue if confirmed, is reported in Volume 15 starting presently at page 1715. The information is minimal but corresponds to what is available. If more information of interest becomes available ahead of release, it will be provided in a news page. This volume 15 is updated on a monthly basis
Where to find the recent issues description area?
The recent issue area is provided at the beginning of Volume 15. It is updated on a monthly basis (whenever possible) and Volume 15 is the fastest growing part of the catalogue and shows all newly approved joint issues.
Has everything been transferred from the old site (philarz.net) to the new one (philarz.com) ?
No, not yet. This is why ‘philarz.net’ will remain open to access for another year. But the missing parts will simply be transferred to an ‘Archive page’ to be created and corresponds mainly to information interesting for historical review. No new information will be added as everything linked to existing joint issues is already in place in the new site. Also it is important to have the old site still open as Google still provides this link in priority due to the high number of older references to this site. This should also be inverted over the next year, with Google serach refering in priority to the new site.
His there a way to make a Search for a country or topic over all web site and on-line catalogue?
There is no general tool allowing to make a search covering both the web site and the on-line catalogue. For the web site the standard “Ctrl+F” function should work. In the catalogues there are two ways to look for any joint issue:
either you know the period of issue, you open one of the 15 catalogue parts and you browse with the Calameo search tool (magnifier symbol on the top right). Don’t hesitate to explore the different tools available in Calameo
or you take a look in the table of content of Volume 1 in which you will find two sections, a) the countries’ index on pages 51 to 71, or b) the topic index, on pages 72 to 93. If you are looking for e.g. all joint issues involving the USA, you will find the answer on page 70. Indeed, there is no automatic link for each individual issue, but this is the best starting point. This list is always up to date regarding the content of other volumes and each modification in the entire catalogue is immediately introduced in this volume 1.
Volumes 1 and 15 are the more often updated catalogue parts and since the inception of this new web site (January 2022), Vol 1 has already been updated four times and Volume 15, eight times. The page of links to sources has been updated more than a dozen times. In this page, unfortunately, over time, links are becoming inactive and the whole list of more than 650 links cannot be checked on a weekly or even monthly basis, but new ones are added regularly.
Is it possible to download or print the catalogue?
No, and this will remain such way. You have to accept that the intellectual property remains with the author. The free access to the cataloge content is a gift to all collectors and the author has no income at all for the work made so far (35+ years of collecting information are available in this catalogue). The 2006 Joint Issue Catalogue (750 pages) was once found as a pdf copy for sale on eBay. A malicious seller had scanned all pages of the printed catalogue and proposed it to eBay buyers without any rights and any contribution left to the author. Several other eBay sellers are doing the same with standard catalogues such as Scott, Michel or Yvert&Tellier in an illegal way. It is as illegal to buy these pdf files, but it is also quite impossible to prevent such thefts. The catalogue printers have so far not succeeded in stoppinf the sale of such illegal pdf files. The reason for proposing the catalogue for free was a kind of answer to avoid such thieves making some profits. In exchange, you have to accept that the catalogue is open only for reading. Access to copies, printing, pdf files will not be possible. This is not making everything impossible as thefts are clever (screen copies remain possible), but at least you know that if one day you are proposed a free pdf copy of the catalogue, this means you are paying for something that is available for free.
I am hoping this helps. We are still looking for suggestions of improvement and always looking for help, in particular if you can bring local information in languages that usually are not retrieved by standard Google functions. Thanks in advance and continue enjoying Joint Stamp Issues collecting.
