Road Runner "Clown of the Desert"

This is a cool Copper Postcard Road Runner engraved on copper by Kopper Card Company. I actually found it inside of a book I purchased at a local yard sale. The seller was a retired professor who was selling all of his many books he has over the years. When I showed it to him he stated "you bought the book so you get everything that comes with it, I want to get rid of all of these books". We both laughed so I keep it as a book marker for my books.
