This is a masonite coke sign that a friend of mine found the other day in a junk pile at a trailer park. He didn't know anything about it except it was going to be thrown away, so he gave it to me. I am hoping someone has information about it and maybe could give me an idea of what it's worth. I looked online & found out it's masonite, but the one online was smaller. This one measures 67 3/4" long and 32" tall. On the bottom left corner it says AM-9-4. Trademark U.S. patent office is written below Coca-Cola. It has some holes and some have been patched, but still displays very well as you can see from the photo. The color is great. What should I do with it? Would it hurt to touch it up with paint or should I leave it as is? Any info would be appreciated.
