Need a hint? The answer is written all over their faces...

Yeap, you guessed it: They are each featured on cards while they are SMILING! Why would I show you a bunch of cards with people smiling on them? Because I received an email from Patricia whose daughter Lucy collects "players who are smiling" among other specific traits. Patricia's interests are more in baseball history, so some of the smiling faces are from days gone by! :-)
