This is a Rare Vintage Aluminum Disposable Ashtray. MAR-VIN Specialty Shop. Bowling Alley Memorabilia. I could not find anything on Mar-Vin specialty shop on Google. It was most likely it was a sport shop located inside a bowling alley. Nice vintage used condition with some discoloration due to its age, but it appears that it was never used. It is just under 3 1/2 inches in diameter.

Please review all of the photos for your most accurate description. Thanks for looking.
