There\'s at least one episode around from the show\'s early weeks with Peter Marshall & Rose Marie as the celebs. My take away from it was how the show was trying to keep up/stay ahead when it came to how it looked. All the prize art cards were in 3-D - the picture of the item and manufacturer logo were cut out and put on a clear piece of something so they could swirl designs behind it and/or swivel the prize itself over a background.
