For some reason I've always called these "push-back" buttons, but most call them tab buttons. Anyway, I've always liked 'em. Here's a few fun ones. The first one is the Wink Gink from Wink soda. The next one is the Mary Blair designed Meadow Gold Ice Cream girl. The third one with Yogi Bear is from the Cedar Rapids, Iowa kid's show Dr. Max. The last one is advertising the Odyssey2 home video game system at the 1982 Knoxville World's Fair.
