Super Rare Bros. YM-901-S

This is it -- the rarest of all Game & Watch titles. The Super Mario Bros. YM-901-S model was only ever awarded to winners of a competition held by Nintendo to promote its (Japan-only) NES racer, Famicom Grand Prix: F-1 Race. Consequently, few were made (just 10,000), making this model highly sought after -- expect to pay big for this.
