IMO it deserves better than to be stuffed away in a dusty glass cabinet in the basement level of the gift shop at the National Air and Space Museum. It should
be displayed over at the National Museum of American History, alongside other pop culture icons like Judy Garland's red slippers and the original Kermit the Frog. I can't help feeling that its current place of display implies a certain amount of embarrassment about it (you almost have to go out of your way just to find it!).
I say: clean it up, and display it in the proud fashion that it deserves.
