Pewter mug, height is 5âe, top of mug is 3âe diameter and the base is 4âe diameter, the Goodyear blimp is protruding from the mug in 3-D fashion.

I acquired this mug in 1985 and at that time it looked as though it had some years on it. I believe that the mug is at least 30 years old at a minimum. The mug was most likely an award given to a Goodyear employee or executive. When I acquired the mug it was paired with another one that was identical to this one. Being a young kid, I just bought it because of the unique way the Goodyear blimp was flying out of the mug. I probably should have bought the pair.
