Poland has been very active in printing cycling related stamps. I have around 35 of them and some of them are very nice, I think. Also Italy, of course, as a great cycling nation has printed several very nice bike stamps. I should post some of them also. When I get my hands on a proper macro lens I will print up some of the best stamps as posters to have as decoration.
Cycling and bicycles, especially track bikes can be very pleasing aesthetically. I especially like the clean look of fixed gear bikes. On my own fixed gear the brakes and the touring bike geometry reduces the aesthetic value a bit. But I do like the big/big gearing (chainring/cog).
This is a Polish stamp from 1960, printed for the 1960 summer Olympics in Rome. It is part of a block, which shows past Polish Olympic medalists. The bike stamp honors the Polish track cycling silver medalists in the 1924 Paris Olympics (4000 m team pursuit). The stamp design is clean and and simple. The rider in the stamp is embossed, which makes it even nicer. The stamps exist in perforated and non-perforated versions.
