I can give you a little history on your sons dx sign. A friend of mine had it on his building in a town called Simpson Minnesota, I am from Rochester MN 15 min. away. He said it was mint when he put it up. Over the years the vines on the building grew over it and attached to the sign. I bought it is a couple years ago from him cleaned up the best I could and sold to a friend of mine in Eyota Mn antique shop. He sold to someone soon after and that year seen it at Iowa Gas show for sale dont know if it sold there or not. Now it ends up at Hershey and your son buys it. I love how this stuff gets around. Enjoy it.
