This beautiful 10 groszy stamp from Poland (1967) features the striking Vanessa io, commonly known as the Peacock Butterfly (Rusałka pawik in Polish). Its vivid red wings, adorned with spectacular eye-like markings, are set against a rich green background, making it one of the most visually appealing Polish issues of the era. Designed by Desselberger and printed by PWPW, this stamp is part of Poland’s popular butterfly-themed series. A classic piece that appeals to both nature enthusiasts and philatelists, it captures the elegance of Poland’s mid-20th century definitive issues.
