CHALLENGE OF THE SUPERFRIENDS Model Sheets

Here's the original model sheets for CATWOMAN & RIDDLER done by Alex Toth for the CHALLENGE OF THE SUPERFRIENDS Cartoon ©1978 Hanna Barbera. As a little kid going to comic book conventions I met Alex Toth & he was really nice to me. I regret that I was too young to think about getting a sketch or autograph but we had a nice long talk. He was really impressed with how I was totally familuar with alot of his "Golden Age" artwork & comics. He asked what comics I was reading at the time & he said he read some of those too, it was cool. This was around the same time these drawings were done.
