Body shape/image worksheet for eating disorders?

I have seen somewhere a worksheet that is used in eating disorder recovery (I've seen it mainly for females) where there is a row of body shapes outlined. Someone would circle how they think they look and then go ask a few other people to choose how they think that person looks. It is supposed to show someone that they way they see themselves is not always the same as others perceive them.

Does anyone know what I am talking about and where I can find this online?

Thank you.
