Funny, Chris! Thanks and hope you enjoy the card and the exhibit. I have heard fantastic things about the whole exhibit from the museum folks and many who've attended. Wish I could make it there myself.
Having that card featured on primetime news programs was easily the highlight of my collecting career.
And if that 7 was dead centered with no tilt, I can safely say as tempting as a dead centered, tiltless '52 Topps Mantle is, seeing as it would cost over 150k I would always take the one at the museum over it
I've had the opportunity to upgrade the corners once now to a higher grade, but it's the freak color on the 4.5 that really sets it apart from even other centered copies. I don't know why its inks are deeper than others, but am just eternally grateful it came off the press that way!
Here's a good pic someone sent me from the museum:
