I grew up with Nakashima furniture! Matter of fact, I'm typing this right now on the dining room table while sitting in a Conoid chair. I also sleep against a Nakashima headboard and we have two dressers as well.
In the 1960's and 70's his stuff wasn't that expensive. My parents had very different tastes, but Nakashima's design was something they both liked (my Mom likes the clean, simple lines and my Dad liked that it was solid wood).
I can take pictures if there's real interest. I've often felt that living with this stuff is what got me interested in woodworking in the first place. My parents got their bedroom set in the mid 1960's. I got to go with them to New Hope, Pennsylvania when they ordered a dining room set and a sideboard. One reason to go was to pick your board for the top. I remember being in the showroom with George sketching, and horsing around with my younger brother. My mother went to hush me, afraid we would wreck something. George stuck his hand out and said "That's OK, let them have fun." I later read about "Kevinizing."
In his writings, he hoped that his son, Kevin, would continue the business, but I guess that didn't happen. His daughter, Mira, is doing a great job and makes both old and new pieces.
