One of my favorite subset/insert sets of the year is the Franchise History series in this year's Topps flagship product.
I recently received the last card that I needed from that subset when Ted of Crinkly Wrappers sent it my way. Ted is so great, because you don't even have to say anything and, bam, a card package is in your mailbox full of stuff you want.
I like this subset so much because it speaks directly to one of my favorite aspects of baseball -- its history. Team history is what gives the best game in the world character. Each franchise has a personality, based mostly on its past. That past encompasses its players, managers, fans, city, and organizational beliefs and actions. The present plays a little part in the perception of the franchise, but only a little. It just hasn't been around long enough.
So, when I think "franchise history," I think of great moments for that franchise. Moments that gave that team a character, a personality.
For the most part, Topps did a good job with reflecting each team's great moments. The cards recognize either a great achievement by a particular team or great players from the team's past.
Broken down, we have:
The Marlins' two World Series titles in seven years.
The Blue Jays' World Series title in '92 or maybe '93.
The Angels' World Series title in 2002.
