Before Katsuhiro Otomo's Steam Boy was released in theaters, a DVD box designed by match55go and titled STEAM BOY Starter Kit came out on June 25, 2004. The set included a short animation film "48 X 61" directed by Rintaro dedicated to Otomo, a talk between Otomo, Rintaro and others, the making of SteamBoy, a promotional clip, a T-shirt designed by Otomo and a sticker with the title logo. I ordered it from Amazon marketplace for few bucks.
