Also what is interesting with Amsels work of the Muppets is that the drawings are copied from still photos of the puppets. I seen for sale on ebay once a very interesting photo. It was two black and white photos of the puppets displayed exactly as they appear in the classic Muppet Movie Artwork, where they are all in the car, one photo was the back two rows, the other was the front characters, Piggy, Kermit, Fozzie, etc. When they were drawn, the two images were joined.
It appears that this image was also drawn from the puppets, Miss Piggy is in the exact same pose as when she is tied up sat on the bail of straw, Fozzie is ordering his Ice Creams, Gonzo, well that needs no explanation, Bunsen and Beaker are peering around the Salon style doors as Kermit discovers there musical water fountain! I still love Amsels style, the characters almost look human, look at Scooters hands!
