Revolver takes a picture every time you pull the trigger

From the Netherlands' National Archive, a 1938 photo taken in New York City of a Colt revolver that has been modified to shoot a picture with every trigger pull. Presumably most of those photos are of people looking horrified and about to say something like, "Oh Christ, you turned your gun into a camera? No, don't point it at me! Ahh!"
