The Croatian and Polish stamps have been issued on December 2, 2021. Each country issued a pair of se-tenant stamps, in miniature sheets of 4 pairs, chessboard ordered. Poland is also proposing a folder containing one perforated and one non-perforated Polish miniature sheet as well as one Croatian miniature sheet. Due to the very low print runs of these folders, they will not be considered as dedicated products of this joint issue. We are expecting that mixed FDCs will become available.
