Just found this as well. Rochefoucauld's Grail.An ancient book believed to be the first written story of the Grail legend, possibly even the origin story It currently resides at Sotheby's auction house in NYC
Correction, it was sold in 2010. Don't know to whom.
Holy crap, this looks familiar! Was looking at images from the Grail, and I remembered this
The book Deidre found at Cumberland Books!!!
The book she found was written in 1474.
She found scraps of a book about 100 years older inside, The Grail was written around 1315-1320.
BTW, am I the only a bit disturbed by how new and clean and white those pages look? kinda like the drawings of Herman the Hippocampus, like they haven't aged at all. They definitely don't look like pages from the book above,or the picture she posted to instagram, but these are the pictures she took at Cumberland.
When the disc changed the other night on Sumner's video, it when from being caked with damp dirt to looking practically brand new.
