If you were VIP, you could get your picture taken with it or the '51 Bowman Mickey Mantle card for free. The Mantle '51 Bowman card is graded a PSA10 and is said to be worth $1MM. The Honus Wagner, 1909 T206 card recently sold for $925,000 and was on display.
I wasn't a VIP, but I was talking to a group of VIPs in the Panini booth line (that's as close as I get to VIP anything). As we were talking, one of them wasn't going to use his VIP "picture pass" and offered it to me! Awesome!
On Sunday, I stopped by the Memory Lane table where they snapped this Polaroid.
