My problem with the stamp
During the will, the late uncle says, "I know what you're thinking. You'll buy a dozen Picasso's and use them for firewood. Forget it. You can't destroy anything that's inherently valuable. That's immediate disqualification."
Well, isn't using the stamp to mail the post card destroying it's value? It got fastened to a post card, and ink from the post office where they stamped it destroyed its value.
