The Most Expensive (and Oldest) Postcard
The picture postcard was bought at the London Stamp Exchange auction on March 8, 2002 by collector Eugene Gomberg from Latvia. It caricatures the postal service by showing post office "scribes" sitting around an enormous inkwell.
It was sent in 1840 by novelist "Theodore Hook Esq, Fulham" to himself. The card also use a Penny Black stamp.
Both the postcard and stamp were authenticated by the British Philatelic Association.
