Factory error vintage Diet Pepsi

[Jonnyjon]

I have an old can that mom brought home from the commissary when I was in grade school. It was empty right out of the six pack and she put it up above the cabinets where it sat for about 50 years or so. It's still in great condition with the ripple style pull tab still in place. I'd post pics if I knew how. Is there a market for such things?
