The house measures 13.5″ x 8″ x 8″. The two sides of the roof rest on two pegs and when removed allow access to the blocks stored inside. There are two holes cut into the top center of the roof that allow the whole house to be carried like a tool box. The bears on the front are original and it says ” Keystone Boston” in the upper right of the siding. The graphics are just like many of the dollhouses that Keystone produced. I have yet to see anything else like this house so dating is difficult.
