Old Johnson Outboard Sign

I found this old sign being used as a cover for a horse shoe pit. It was originally used at my dads store back in the 60s or 70s. It was a lot of work to get it out of the weeds and brush that had grown over it. There is one more just like it over the other pit. I believe that is the other half of it but I have not dug it out yet. I can't find one like it online.
