On January 5, 2022, appeared the first joint stamps of the year. As for previous years, China PR issued two stamps at the occasion of the change of Lunar calendar, in 2022 Year of the Tiger, at the same date as Macau, issuing four stamps and one souvenir sheet with a round stamp. A high number of countries are issuing stamps at this occasion, but Macau and China are the only postal administrations which got used to produce a mixed first day cover with the stamps from both countries (not including the souvenir sheet).
Rindert Paalman (the Netherlands) noticed that the issue of 2021 (Year of the Ox) was missing in the catalogue. This will be corrected within the next days and will correspond to an important addition which will affect for the first time the upgrading of one catalogue volume. As Macau and China PR are politically dependent countries, these issues will be filed in the category [D].
By checking for earlier issues reported in the catalogue, it appeared that for the year 2019 (Year of the Pig), the entry was mistakenly filed as [P20190105] which has to be renamed as [D20190105].
A check of Lunar Year stamps issued by China and Macau before 2019, showed that both countries issued stamps usually on January 5 of each year, since at least year 2000, but we have not seen mixed FDCs for such products. So, earlier Lunar Year stamps from these two countries will not be reported in the catalogue, unless someone provides proof of the existence of mixed FDC covers corresponding to these stamps.
