American Girl is huge in the world of my nieces. I guess rightly so, but the intrigue to me pales from what I remember them as during my youth. I remember a catalogue coming in the mail with pages full of girls with their dolls. The doll respresented characters from history, there were books about their experiences, but the coolest part: there were period appropriate outfits to match the dolls! What an opportunity to pretend. I think Mattel really missed something when they retired these.
