The 20 gr brown stamp depicts Warszawa (Warsaw) with a dramatic medieval city wall and a procession of armored riders approaching the fortress gates. Designed by W. Chomicz, these stamps capture Poland’s rich urban history and architectural heritage. Their classic engraved artwork and historical themes make them appealing additions for collectors of European city views and architectural philately.
