Once while doing a search I stumbled upon this unknown (at least to me), Choppers Magazine T-shirt art.
I can tell by the art's style it was done by Robert Williams. I don't think Roth ever made it available. Possibly because the ornate lettering on top of the art is so busy making it hard to read. Still it's a cool drawing.
Been drawing as long as I can remember and into bikes since 1967. I do other kinds of art but enjoy painting and drawing motorcycle related stuff the most. I do commissioned artwork and sell limited edition prints.
