Vintage Chevrolet 'OK' Used Cars Dealer Porcelain Sign

This is a circular advertising sign associated with the Chevrolet 'OK' Used Cars branding program, which was a prominent marketing campaign used by General Motors dealerships throughout the mid-20th century. The sign features a convex (dome-shaped) construction, suggesting it may have originally been part of a larger neon assembly, a pedestal stand, or a porcelain enamel display. The color scheme is a vibrant primary palette: a bright yellow background, bold red script for the 'OK' lettering, and navy blue for the border and the block-text words 'USED' and 'CARS'. The 'OK' logo is characterized by its distinctive blue drop-shadow, which adds a sense of depth and mid-century graphic flair. The piece appears to be made of heavy-gauge steel with a vitreous enamel (porcelain) finish, known for its durability and high-gloss sheen. The surface reflects light sharply, indicating a well-preserved or potentially restored finish. There are no visible chips to the porcelain edges or mounting holes in this view, though slight surface variations and reflections are present. This style of signage was most prevalent from the 1940s through the 1960s. The quality of the lettering and the smooth transition of colors are hallmarks of professional automotive advertising of that era, though buyers often check for maker's marks like 'A-M' or 'Walker & Co.' along the bottom perimeter to verify original manufacturer provenance.
