The 1962 dream house was the first Barbie's house offered by Mattel. It's made of cardboard, so it may be hard to find to find in a very good condition - pictures bellow are from a eBay auction, it seems in a very good condition for its age.
The house also included some furniture as show in the picture, all made of cardboard as well
I wasn't crazy about this house as it's made of cardboard. It seems so fragile, it may be impossible to play with, I'm glad nowadays they use had plastic, can you imagine? (I used to love paper dolls, but after while playing with them was a challenge as the head or feet wouldn't stand alone.)
