Super Mario Bros. [Model YM-901-S]

Released on August 1, 1987 in Japan.

This is the rarest of all Game & Watch games, the only way to get this game was to be a winner in a competition that Nintendo ran to promote the Famicom (Family Computer). The competition was held in 1987 and 10,000 of these special YM-901 games were given out.

The winners of Famicons F-1 Grand Prix tournament got a yellow-cased version of Super Mario Bros. that came in a plastic box
modeled after the Disk-kun character Nintendo used to advertise their Famicom Disk System.
