Barbies in the 1950s TOTALLY reflect Gender Roles. The barbies became a young girl's best friend. Most of the toys constructed young girls how to become a " good mommy." It would help them imagine their life.
And, then we had the boy toys like the GI Joe. This toy represented that men were strong, had courage, and was "America's Movable Fighting Man." This was new territory in imaginative play for boys - G.I. Joe was not a "doll" he was an "action figure."
