Went and ate dinner at my mom's and she gave me this poster that she got at an auction over the weekend:

I've never seen anything like this, I have no idea if this is an original or a reprint. Either way I know it is pretty old from the paper. I'm gonna do a little research and see what I can find out about when I have time.
You have a very nice mom.
