Here's an interesting one:

Apparently this was the only Lionel Carter auction that was shilled. I very much doubt that Carter himself was involved in the shilling - I doubt this would have been his one auction to choose to shill. I would guess, instead, that Mastro had knowledge of the highest bid and then did this in order to increase the premium.
