This fist was originally in an ancient newspaper smashing prices or something but with a bit of rotation and a whole lot of editing it became a generic "power" fist. It could be used in a propaganda sense I guess, or in any other sort of sense. Heck, even a smashing prices sense if needed I guess. Hmmm!
