The Penny Penates is a postcard that was posted on 14 July 1840 to Fulham in London. It was addressed to the writer and practical joker Theodore Hook, who was probably also its sender and artist. The hand-painted design on the postcard shows an image of post office clerks sitting around a giant ink well. 
The postcard was discovered in 2001 by a stamp dealer while he was examining a stamp collection, and verified by the British Philatelic Association's expert committee as genuine and the world's oldest known postcard. It is also the only known surviving example of a Penny Black stamp, the world's first adhesive postage stamp, used on a postcard. It was sold at auction in 2002 for £31,750 (US$44,300), the most ever paid for a postcard.
