In the hours before the official show opening, there had been a green tarp covering that section of the booth, but at the opening bell Blowout owner Thomas Fish personally greeted each and every buyer of the Blowout MegaMix to help them make their choice of one of 600 serial-numbered packages, see what was inside and help them collect their findings.

The scene you see above? That's The Boss in action with the collector to the left getting either a box lot of the pictured item or a sealed case. Other surprises in these $100 boxes -- besides the Blowout shirt, a VIP party drawing entry certificate (drawing is Saturday) and even a little sugary Megamix extra -- can include autographed jerseys from Hall of Famers, a guy you might know named Shohei Ohtani and even autographed baseballs from a few Atlanta Braves rookies. (That's all they would tell me in advance -- it's that top secret and the fun is in the mystery.)
