On Saturday I went to the local Target which is the only retailer left in town that had any Garbage Pail Kids Flashback cards left. There were 10 packs left in a gravity-feed box so I bought half of them and when I opened the 5th pack I was surprised to find a SKETCH CARD!!
It was a Layron Dejarnette sketch. He worked on the 5,6,7th ans series.
Here's a pic:
Here are some more of Layron's flashback sketch cards.
Here is one of my favorite illustrations Layron did for the Gpk series. He also did work for Hollywood Zombies cards.
