Peer Clahsen x Creative Playthings

Peer Clahsen designed this etagen-puppenhaus (l) for Naef around 1970. I'm going to say he also had something to do with this one for Creative Playthings (r), who frequently collaborated with Kurt Naef.

Update: Turns out it wasn't Clahsen or anyone at Creative Playthings. The original open-plan dollhouse was designed in 1968-9 by _____ ________. I'll fill in the blanks once I make the rounds on eBay. ;)
