I bought this tin Sunshine Beer Sign last night up in the coal regions of Pennsylvania from a guy who said he used to own a bar and a beer distributor back in the old days. It isn't a tin over cardboard but it appears to be tin wrapped over tin. The sign is in near perfect condition and I've never seen one like it before. The bottles on the sign read "Sunshine Barby's Inc." which I know was a brewery in Reading, PA and later became the Sunshine Brewing Company.
Does anyone know anything about this sign? I'd like to put an approximate date on it, the rarity of the sign, and any other facts that you might know about it.
