Rat Fink is one of the several hot-rod characters created by one of the originators of Kustom Kulture, Ed "Big Daddy" Roth. Roth's dislike for Mickey Mouse led him to draw the original Rat Fink art. After he placed Rat Fink art on an airbrushed monster shirt, the character soon came to symbolize the entire hot-rod/Kustom Kulture scene of the 1950s and 1960s. Roth is accepted as the individual who popularized "Monster Hot Rod" art form. The Rat Fink Art depicts a green, depraved-looking mouse with bulging, bloodshot eyes, an oversized mouth with yellowed, narrow teeth, and a red T-shirt with yellow "R.F." on it.
