Early 1900\'s Aluminum Business Card Samples, 12-Different In Original Alum. Box. For Sale

Early 1900\'s Set Of 12-Aluminum Novelty Business Cards Samples In their Original Aluminum Box. The subject of the cards is risque cartoon humor, and the back of each card is blank. Each card is approximately 3 1/2 inches by 1 7/8 inches in size and range in condition from good to very fine condition, and the box is in good condition with some wear from use. I have seen most of the pictures on the samples on aluminum business cards in the past.
