I always liked the green dinasaur from Sinclairs.
How about S&H Green Stamps?
On Friday nights here in the late 60's after football games it was common to go to a hamburger place where you actually sat down.
No "drive-through" windows except Jack-in-the-Box which were just getting started. The name of the one we frequented was called KIP's
which had this weird looking figure on the lawn holding up a finished burger. And underneath it said, "Kips'....Home of the Big Boy" And they were right! those burgers were huge!
