How do you become an American girl model?

You can't
Well, the have staff members who write the stories for ag and the put it upon a board and pick the best.
You can't. It is chosen at random.
you can't; the company just makes a person up.
You cannot!!

The AG writers make up a story, that fits the time period. I don' think they base it on real people with the names they pick. They create the name and story...
well the American girl Lanies Back yard contest has past already but if you are talking about the contest of how they determine the girl of the year well they just choose some one which they make up and then they make a story with morals for it

You can't, the American girl doll of the year is not real, she is a story character.

But you can enter the make a poster contest. There is a contest this year where you make a poster that has to do with stopping bullying and creating a more peaceful world.
Unfortunately that cannot be done.
You can't.
Ummm you can't, the Girl of the Year characters are fictional.
