Rat Fink designs

California car art designed by Ed Roth originally back in the late 60's but rose to fame in the 70's. Nothing like it even today. Back in the late 90's a team. Hardy boys, tried to duplicate the style but did not have the subject matter to make a dent in the industry. To understand what I am saying match 3 pieces of art from each artsiest. Where is there a re-occurring theme, and what is it?
