Rare Original plexiglass arcade marquee from Mario Bros (1983). This is the first appearance of Luigi and the third appearance of Mario in an arcade game. It is also the first game in the Mario series, preceding NES Super Mario Bros by two years. The vast majority of Mario marquees out there are reproductions. 

Note that this marquee is the rarer wide version without the 2-player bubble. It has been slightly trimmed on the left and right sides; probably done to fit a smaller arcade cabinet.
