BLUE Porcelain Street Sign Enamel Over Metal Double Sided DELAY AVE Vintage I really like this sign, it was a constant in the homes that we have re-done. I believe it to be in excellent USED / VINTAGE condition. There are enamel chips, but for the most part it isn8n really good condition. I believe that it is from California. Double Sided, I don’t know if there were end caps or how it was mounted. It measures 24″ long and 6″ high.
