This poor kid can barely reach the pedals! How on Earth did he get up on that thing? This moody stamp was Guinea Española's (Spanish Guinea's) contribution to Dia del Sello, World Postmark Day. The celebrations are legendary! What's the deal with the giant front wheel I hear you ask. In the days before gears were introduced to bicycles, manufacturers increased the size of the front wheel as a way of increasing speed. The name Pennyfarthing comes from the British coins and refers to different wheel sizes. This sort of bike always makes be think of The Prisoner. Be seeing you... in this unusual t-shirt.
