Been meaning to mention this since it started last week - there's a new Prestige Collectibles Auction going on until May 15. Details are here.
One really cool item up for auction is a 1962 menko card of Larry Doby, when he played for Chunichi. The auction description is incorrect when it says that Doby is the only US Hall Of Famer to have played in Japan as Rich Gossage played for the Hawks in 1990. However, Gossage didn't have any cards, so Doby's the only one you can get a Japanese card of.
