I was in Dublin last week and obtained the final stamps issued in 2015.
One stamp commemorates Saint Columban but the other three are Christmas issues.
The small stamp (national rate €0.70) is only available in booklets. The Philatelic Shop at the General Post Office sells them as a pair…a service to Collectors.
The other stamps are “Stamps on a Roll” (SOAR) and available in any value. The Post Office clerk simply prints out the required stamp…national or airmail or a small amount to make up postage and also depending on weight and size of package.
Again the Philatelic Shop sells these stamps as a pair.
The stamps above are “mint”. I have received the second set of these stamps I posted in Dublin.
