It appears that the two page handwritten letter (covered previously here) was withdrawn from the sale just before closing, and is no longer listed at all on the RRAuction website. The history page for that auction no longer shows item number 520 at all: http://www.rrauction.com/past_auction ... =430&order=Item&InvPage=7

I would assume there was an invisible reserve on the item which it failed to meet, which is not surprising given how expensive the letter was at Christies the year before.
