Here are a couple of aftermarket bingo backglasses I have.
They are badly silkscreened onto plexiglass. The graphics are a crude rendition of the original bingo backglass art.
The colors are neon like. They give a festive carnivalesque feel to the bingos. All and all I don't hate the look they give to a game. Anyway, a bad backglass is better than no backglass at all. The Surf-Club backglass shown below is on the game I like to bring to pinball events, shows, flea fairs and swap meets. Just the backglass by itself is a conversation starter.
These backglasses were made by a longtime Bingo machine distributor and reseller in the greater Montreal Qc. area.
