My friend Lemoncadet bought lots of Petite Princess furniture. She found out there was a series of copies made in the 1960's. The original chair made in Japan is on the left. The copy made in Hong Kong is on the right.
You can see the difference of the markings on the bottom.
The original Buddah on the left looks happier.To see her flickr stream here: http://www.flickr.com/photos/lemoncadet/5504334755/in/photostream/
