The product is a vintage Chicago Pneumatic advertising retro sign from the 1920s-1940s, featuring a theme of gas and oil. This collectible sign is a piece of merchandise and memorabilia that represents the advertising efforts of the Chicago Pneumatic company during that time period. Perfect for collectors of vintage signs or anyone interested in retro advertising, this sign captures the essence of gas and oil promotions from the mid-20th century. Guessing oil based paint. Definitely not the best job. And very noticeable. But still.. Very old thicker heavy gauge metal. Embossed letters. 28″ inches long. 2.5″ tall.. One corner has noticeable moderate wear on edges and thickness of metal. From rust and aging. Guessing these were the name plates that were with the industrial compressors The company made in the 1920’s.. ?? Please view pics for your opinion on condition and measurements. Please expect vintage items that may need cleaning or repair. Will receive items in pics. Thanks.
