Honestly, this is a money grab for Topps. The regular season factory team sets go for $4.99 and there are 17 cards. The World Series edition, with two less cards is going for 20 bucks. Four times the price for two less cards. A money grab.
You should have noticed right away that most of these are aligned horizontally. That's a bummer for me. The cards go in sheets in a binder and the sheets are vertically aligned. When I want to look at theses, I have to turn the binder instead of just being able to page through the sheets.
The backs have a small write-up and some game details
