I originally posted an entry about Stanislaw Schmidt's collection of table tennis balls back in September. The post can be found here. His collection includes over 1,000 unique table tennis balls. You can see the collection of balls at the Web site ttballe.org. The balls are categorized by rating, size, ball color, stamp color and design, number of stars, country of origin, and information about the producer. If you are a collector, this is an incredible resource. He exchanges balls; just look for the exchange link under the individual balls.
Here are more my favorites: a 38mm Schildköt ball from Germany; a 38mm Rabbit ball, country unknown; and a Giant Dragon 40mm ball from China.
