Trade You an ATL for an SFO? Airports Unveil Trading Cards

Baseball teams have them, some police forces have them and the TSA's K-9 unit has them.

Now more than 20 North American airports have trading cards too.

Unveiled earlier this month, each card has the look and feel of a traditional baseball card. But instead of portraying a rookie player at bat, the cards in the North American Airport Collectors Series feature an iconic image of an airport on the front and geographic information, fun factoids and historical tidbits about the airport on the back.
