This cancellation from the Soviet Union, 1977 (with a stamp from 1966 though) shows a juggler on a slackrope. I can't read Russian so I don't know what the picture refers to. I have scanned this from the Dutch magazine Filatelie (2002 05), from a 6 page article about circus stamps.

Back to Unicycling in various media (books, newspapers, stamps, internet).
