BWA prices always amaze me. Just when I think that I've seen the highest price ever on a cel, someone comes along and plunks down a greater amount. That Madoka hanken from Kimagure Orange Road ended at something like 3,400,000 yen. I mean, yeah, the pose and douga were drawn by Akemi Takada, but you could buy a hand-drawn Takada sketch for far less than 28K. For 28K, I'll sell mine.
I tried to win the Hiiro no Kakera sketch because I'm a fan of Yone's character design (although I loathe the HnK franchise) but lost out. Not that I'm too terribly disappointed with that ; I put the funds towards a SakuraCon charity auction win.
Didn't a lupin cel setup from Castle Of Cagliostro end up at over 8 million yen, with the exchange rate that time comes out to be at least $100k? I remember someone here edited wiki with that as the most expensive anime cel to date?
