The creep factor is if you know what anthropodermic means....
I certainly do, and is that even legal to sell? (I'm guessing the age of the item makes it okay)
As an antique, yes. Anthropodermic bibliopegy is actually more recent and more widespread than some might think - there are some anatomies that were created in 19th C. prisons where the deceased prisoner was not only the subject matter.... And there are the rumors about the concentration camps in Germany during WWII. (I seem to recall a book from Buchenwald that was auctioned off during the 1970s, to benefit public television....) Then there is the joy of finding such a book lying in the street
Memento mori are amazingly macabre by modern standards anyway - Sedlec Ossuary is a sterling example. People used to wear locks of hair from deceased parents, and I have seen several rings made from sections of leg bone.
