Preservation

When I tore my 65 Barracuda down, I saved "everything" I found in the car and I mean everything...coins, screws, receipts, notes, gum wrappers etc. and the grand prize...a complete, in great condition, broadcast sheet. I would like to hear some ideas about the meaning of the numbers written on the floor pan above the fuel tank. The Numbers 12 -12- 22, could they be "graffiti?" Maybe an assembly line worker's birthday. I did the math...in 1965, the worker would of been been 43 years old. Sounds about a right age for the era. If it is birthday graffiti...My birthday is also December 12th. A cool coincidence??? BTW the numbers will not be painted over.
