Hand-painted Vintage RESERVED Wooden Sign Mexican black clay I'd think late 19th centuryI like to imagine this sign once hung above a big back booth at a local diner, forever reserved for for a local VIP, maybe a small town mayor, or perhaps a beloved waitress who had worked there for 50+ years. Now I might hang it over a favorite chair, or on the guest room door in anticipation of one day in the future a dear houseguest! 15" x 8 1 4" x 3 4". Wired on the back for hanging. A few scuffs and scrapes here and there, as there should be.
