My original tumblr post was here. This image was originally posted by Republic Domain! who gives this explanatory text “Backglass from Gottlieb’s Centigrade 37 pinball cabinet, 1977,” as well as a reference to an originating article at Gizmodo. The image comes to us via Reginald Juice.

Interested viewers can refer to the entry at the Internet Pinball Database on Centigrade 37 for further details on the game. That article includes an image of an important detail on the backglass.
