According to Yahoo!, John Lennon's stamp collection will be on display at the Smithsonian:
Beatles star John Lennon collected stamps as a schoolboy — and the public will soon have a chance to see them. The Smithsonian's National Postal Museum announced Friday it has acquired Lennon's stamp album and plans to display it in October.
..."We're tremendously excited at the prospect of exhibiting John Lennon's boyhood stamp album," curator of philately Wilson Hulme said. "I hope it will inspire new collectors. There are people who think stamp collecting isn't cool, and maybe this will cause them to think twice about that. It just doesn't get cooler than John Lennon."
Mr. Hulme strikes me as the optimistic sort.
