Correct Craft Marine banner / sign question

Hate to make this my first post but I don't know anyone else to ask. I collect old outboard oil cans and signs but I can't find anything out about this one. Has anyone seen this banner before? I've looked at every forum and FB page I could find but see nothing. I'm starting to think it's pretty rare since there's no record of them. I got it because it's a Tennessee sign and I always get any advertising with Tennessee on it that I can find and afford. I tried to find one of the cans just like on the banner but they're hard to find and priced up there. I appreciate any information anyone may have. It's around 5'x3' in size.
