These round, tin lithograph signs have tabs that would have been put on various mattresses made in Chicago by the Kinney-Rome Company. This one was for the "DeLuxe mattress. It measures 4&7/8 inches in diameter. The tabs are intact, and there are a few bends, but the gold and black lithograph front shows little wear. There is some light rust on the back. I have not cleaned, or polished this sign.
I currently have several pieces of vintage advertising, including other tin and porcelain signs, in my shop, and am happy to combine shipping when they can be safely packaged together. To see them all, type, "advertising", or, "advertising sign", in the California Girls search box at the top of this page
If you are ordering more than 1 item from my shop, wait to pay until I send back an invoice with the combined shipping discount.
