I think anything signed by Rickenbacker is priceless 
My uncle has a German sanke card signed by MVR.
I think he must of got it when he married Erika who at the time was his 2nd wife and she was part German.It came from her father i believe.
But it's really old and in a frame still in top shape.

WOW! Talk about priceless. That sanke card signed by MvR himself has got to be worth quite a bit! Could your uncle adopt me?
