I don’t know if these guys are mobsters. There is zero information on this card. It’s a real-photo, for sure, but not a Kodak one, so my dating information is useless.
The guy standing is well dressed. Suit with suspenders and one of those fashionable (then) shorty ties. But look how the cuffs are on the sitting guy’s pants. Maybe he wanted to show off his shoes.
The paper on the floor is pretty shabby. It looks like a corner chair that he’s sitting in, or maybe he’s just sitting sideways in a regular chair.
Grim looking guys, though.
