It is not every day that one comes across of complete sheets of municipal tax stamps. Gouda tax stamps are not that common at all.
This complete sheet of 32 stamps of ƒ 0,05 (probably printed at the beginning of World War Two) has a very interesting error (see detail). One stamp in the sheet has the value ƒ 00,5 instead of ƒ 0,05! Most interesting!
