My daughter, who turns four in March, is quite the little collector. She has a binder full of pages containing Red Sox and Bruins cards. Her favorite players are Jon Lester (Sox) and Andrew Ference (Bruins.) I introduced her to cards early on, including handling raw T206's. I figured this way she would learn to respect them. So far, so good.
Two weekends ago I brought her to her first card show (Woburn, MA.) She had a great time picking out some new cards for her collection. She couldn't wait to get home to place them in her binder.
