Hey! Playmobil has some new Micro World releases this year. They now have the Modern House available in this tiny scale. I had to buy that. I usually buy these pieces to use as modern toys inside my dollhouses. You can see the Noah's Ark in the modern nursery here.
I've been hoping for a long time that someone would make a 144th scale version of the Kaleidoscope House. I had even anticipated it being an accessory back when the house was being produced by Bozart Toys. I think it would be so very cool to have that sitting inside the 1:12 structure. Sigh.
