Vintage Chevron Oil Mug Unique Heavy Acrylic Crystal Clear Lucite Advertising

This is a really unique item, I could not find another like it. I am guessing this was a limited run to celebrate the production of some type of special acrylic at Chevron. It is an acrylic or lucite polymer which is heavy and crystal clear. A perfect gift for dad, a gearhead, chemist or advertising collector. Condition*: Excellent condition, no chips, cracks or staining, a few tiny scratches, mainly along the bottom edge. Size is 4" h x 3" w, holds 10+ oz. Is this your thing of beauty?
