Strangest thing found in your A body???

Replaced the carpet in my daughters (now wrecked) 66 Cuda, which necessitated removing the rear seat. We found a small box of candy cigarettes, a couple of matchbooks, a toy plate, some old socks, and lots of debris from the seat. Also an old fountain pen, part of a "protected" card (warranty?), and some old gum wrappers.

Where did that car come from? We have one of these here, still open.
