This listing is for an advertising mirror that measures 2-1/2" in diameter. It was put out by the Sears, Roebuck and Co. to advertise it very generous return policy and also to promote its catalog. I'm guessing its age to be in the 1940s or possibly earlier.
The advertising side is in excellent condition with no chipping or stains. The mirror does have black dots.
Sorry to international shipping on this item.
