Jim, very cool. You're unusual for two reasons- obviously, owning the car for that long, but also for having the foresight to save all that stuff. Too often and too easy it just gets tossed.
pedlondarite, there was a bunch of little stuff in mine too- coins, bottlecaps & such. Strangest was the little mouse skeleton.
bird of fire69, my Mustang is a California black plate car. When I cleaned and repainted them, I scraped the sticker pile down and got all the way back to 1965- about a quarter inch of stickers!
And the glovebox is still locked. I don't have a key for it, and haven't gotten around to breaking into it! Who knows what's in there?
