Hi everyone I came acrossed this sitting on a gentleman’s old lawn mower in his back yard he had no clue he had it ! Yes that much clutter lol. I can’t find anything really on history of this company. Looking for era of sign and possible if it’s rare or really worth anything. Not looking to sell it just need some help with its history thank you all very much
