That was the first decal I ever bought. Put it on the passenger side vent window of my '61 Ford that I drove while in school at USC. Still the best decal ever!
I know it is older than my time there in the late 70's, but it too was the decal I displayed on the windshield of my 72 Toyota Corolla (no a/c and an AM radio). Good memories. Thanks for posting it.
