Measures just 2 1/2" x 1 1/2"; probably came off an old piece of restaurant equipment. Vintage 1948 Brass Metal Sign Label Ace Fixture & Equipment Co. Denver Colorado. Nice graphics showing Ace of Spades. I did a Google search of this company and the results were all dated 1948 & 1949 so it certainly has plenty of age. Fine original condition with a nice aged patina - see photos.
