Budapest has many small museums dedicated to specialized (or perhaps obscure) subjects, and the Stamp Museum, located on a side street in the old Jewish quarter, is certainly one of them. Though you might not suspect it from the unassuming exterior, this museum holds a spectacular collection of more than 13 million stamps, making it one of the world's largest. The stamps are from all over, but naturally the Hungary collection is the most complete. Leafing through the ingeniously designed racks of stamps here, you can pick up the story of Hungary, from the Austro-Hungarian stamps, to those with Lenin and Stalin, and on to contemporary stamps and subjects.
