One of the gems I found at WonderFest USA in 2007 was an original sculpt by Japanese sculptor Yoshinore Yatake of Accel HP. The sculpt is called "Original Character #3 Future Girl". Yatake-san was there in person and brought several gorgeous kits along. I was fortunate enough to score one of these originals before they sold out (yet another reason to grab an Early Bird pass!). The kit is 1/6 scale and cost $100.
