I have the original signed Clue-like print hanging in my office. Kind of cherish it even more now, not a big signed memoribilia guy and my only other signed framed items are Radiohead and Refused prints. This one is as sentimental to me.
I do actually have the Nighthawk one also, have been meaning to pull it out and get it framed. All those prints were odd sizes though so frames are expensive for them.
