Chris Olds over at Beckett had a preview gallery up on his blog yesterday. There were some different aspects to Series 2 over Series 1, but overall there were many of the same inserts.
Here were two of the base cards that I noticed were missing from Series 1.
I like how both my guys are flying through the air and also how Derek Jeter looks like he kicking Shane Victorino in the face.
Two of the new inserts include Vintage Legends where legends appear on cards not from their era. Beckett uses the example of Babe Ruth on a Topps 1999 card or Cy Young on a 1987 card (you can see more pictures at this link).
Topps 2020 is the other insert set, which has a different feel than a traditional baseball card, according to Olds who broke a box of this stuff.
Of course, there are going to be rookie redemptions on the set because it's an easy way to get the cards of some of the rising stars in a set without having to commit to them in the first go around.
Topps Series 2 is set to release around May 26.
