This is a set of nine postage stamps from Poland, issued in 1966 featuring forest birds. These stamps are mint never hinged, meaning they are in pristine condition and have never been used. The stamps showcase various bird species and are a valuable addition to any stamp collection, particularly for collectors interested in bird-themed stamps from Poland. Each stamp is a piece of history that captures a moment in time from the animal kingdom, specifically focusing on the beauty and diversity of birds in the forest.
