Despite the fact that the mini-omnibus series related to the stamps issued by Ascension Island, Bahamas, Falkland Islands, South Georgia and the South Sandwich Islands and Tristan da Cunha, also associated to the Isle of Man, was considered as a non-approved joint issue [N] and will not be described in details in the catalogue, it appeared important to complete the information provided in the previous blog page. Actually, the apparently se-tenant issue released by the Isle of Man, triggered attention and raised more questions. So, a more detailed presentaion and additional explanations were provided by Adam Paish (UK). Here is what he says:

Nothing is ever quite as simple as it seems! My correspondent at the Isle of Man Post Office and I had a lengthy chat yesterday [April24, 2026] concerning some of the information relating to this mini-omnibus series in order to avoid it ending up catalogued with inaccurate data.

The five overseas postal administrations (Ascension Island, Bahamas, Falkland Islands, South Georgia and the South Sandwich Islands and Tristan da Cunha) issued four stamps each, and each individual stamp was issued separately in sheets of ten identical standard gummed stamps with traditional perforations. The widely circulated ‘mini-block’ illustrations were based solely on the press images originally provided by the printing company, Cartor Security Printers.

The Isle of Man issued a set of six stamps dedicated to the late Queen’s Fashion Legacy, the theme of a special anniversary exhibition which runs from April to October 2026 at the King’s Gallery in London’s Buckingham Palace. Again, these stamps were released separately in sheets of ten standard gummed stamps, and the design of the 93p denomination is based on a Marcus Adams photograph. 

Within the ‘limited release collectable’, the twelve-stamp multi-territorial Marcus Adams sheetlet is in reality the left-side panel of a double-sized and folded pane of 24 self-adhesive stamps with die-cut perforations. The right-side panel incorporates twelve self-adhesive Isle of Man stamps (with designs based on previously issued Queen Elizabeth II stamps) and digital non-postal reproductions of the six 2026 stamps superimposed with a facsimile First Day of Issue postmark.

In other words, Isle of Man has produced a booklet sold at £35 that contains, on top of the Fashion Legacy stamps from this postal administration, some stamps (not all) from the five other postal administrations issued on April 21, 2026 (without doubt with their authorization), but this item cannot be purchased from them. It is only available from the Isle of Man postal administration and was produced in limited number. This is another reason confirming that this item was produced purely for marketing purpose and remains far away from true joint issue. Each collector will have to decide if this item will have to be part of his collection. Thanks Adam for the update.
