I ran across this postcard on Halloween before my incident and just had to have it because I had never seen one like it before. It has the Oklahoma State Flag on the front of it, but what makes it so different is that it is Copper.the card itself has a sheet of Copper with the Oklahoma state flag embosed into it and then the edges are folded tightly over the edge of the postcard. The back is typical card stock. The copper front has got several wrinkles in it which I don't know, but presume, maybe from waer and tear from poor care or if maybe they are typical of the manufactureing process. If anyone else has any like this I would really love to see them.
