Evinrude outboard motoring sign

Bought this sign from a gentleman who said it was in his grandfather's store. When his grandfather past away, it was given to him and he kept it until he wanted to sell it. I bought it this year from him and was elated to get it! Have not measured this sign yet but is roughly 3 by 5 feet. It has original markings on the back. Has some rust on the edges and on the sign itself. I have at my lake house and love all fishing memorabilia and signs.
