Don't know much about these items. The pieces directly behind the dolls are metal, it's hard to read though some say Mattel, also I looked behind one of the taller boys doll back and took a photo of the maker and it said Town Swuarenot sure if the others are the same though they have a lot of the same character. So I have 11 metal pieces, the bathroom is a porcelain. All the rest are wood accept 2 vintage looking plastic pieces.  Not sure who made these. They do not say China on the furniture..no markings accept the metal pieces say Mattel and some others .you get all of it.
