^ The US$40K (adjusted for exchange rate) item wasn't a shikishi, but rather an original page of manga artwork. It was supposedly drawn by Osamu Tezuka, and anything even remotely affiliated with Tezuka always goes for stupid high prices. Other than the tape burns, it was in good shape for its age. Not to mention that this particular sheet featured Princess Sapphire, and she's often referred to as the mother of the 'shoujo' anime genre. If your collection is focused on items of historical significance, this would be a piece to get.
The prices were expected for the higher priced original artwork, with the Rumiko Takahashi colored sketch at $16K, the Takeuchi Usagi sketch at $6.5K and the Ranma Takahashi sketch hovering in the high $4K range. The eroge shikishi, particularly the
Koihime Musou sketches, also did quite well. I did think it was interesting that no one purchased the Namori sketch, despite her
Yuruyuri anime having quite the following.
I don't think Mandarake verifies everything that it sells simply due to the volume that it sells. In most cases, it's not necessary to verify as most counterfeiters focus on only a handful of very famous artists. I also don't think it would be possible to verify the majority of the original artwork for sale. Part of this is because the person selling it may not be the original owner and the other part because the records associated with this item may have been lost. For example, unless someone actively catalogs the ads featured in weekly/monthly magazines that show smaller versions of the original sketches being offered, unless the accompanying congratulatory letter (which sometimes isn't included in the first place) is included, it's the seller's word against that of the expert. This is further complicated by the fact that, in some cases, some contests offer more than 1 sketch from the same artist, but only one of the sketches is shown. How then do you determine authenticity? In the case of shoujo/josei/yaoi artwork, those artists typically put a lot more detail into their sketches, meaning that someone very familiar with their style can easily pick out the counterfeit. That's a lot more difficult with artists like Hayao Miyazaki, whose Totoro sketches are comprised of just a few squiggly lines. Some artists, like Akemi Takada, will personally notify and/or post if they see a counterfeit being sold on a high profile auction, but many either don't recall or care enough to keep track of what artwork attributed to their name is being sold.
