WAH's Revolver, Beaten Up, Iconic Feeling Old Photo Print on Card

I know little to nothing about guns, but assume the WAH on this revolver is the monogram of its original owner. Printed on card, like a real photo postcard, but with blank back--perfectly matter of fact, like a salesman sample. Someone certainly carried this card around for a while, as it is all sorts of worn and creased. The image (and the monogram too) makes me think Andy Warhol (who did not have a middle name.)

5" x 3 1/2". Worn and creased as evident, which feels rather all of a piece with it.
