Bank of Poland bag (name in the IIRP period notation).
Made of thick, strong paper.
Preserved in very good condition.
Implicitly we assumed that it was for 2 zloty coins (Head of a Woman), but there were suggestions that it could just as well have been for 2 zloty banknotes of 1936 issue (format-wise it is just as appropriate).
Undoubtedly a rare curiosity.
Format: 104 x 174 mm.
