You get everything thing that is in the pictures -- the house was a late addition so it is only pictures on its own not with the set but all included. The plastic pieces look to be mostly in good shape but everything needs to be washed after 50 years of storage.
The set was clearly played with so some of the bits might have wear or damage from play but I did not see anything significant. The mansion was stored separately assembled and it has some rust on the roof (see pictures) and the underside. The box is worn -- it looks like it came from the 1960s and was played with. It is soiled and has some rips (see pictures). Still this looks good and there is nothing like it on the modern market. The box will be huge to fit all of this in.
