This crap isn't OLD
This is old and the only known complete first edition of Nostradamus from 1566, one of the top selling authors in history, only the Bible and Shakespeare have sold more books in the 20th century than Nostradamus as far as dead writers go. When you realize how Nostradamus has been in almost every language now for a long time and how many people have written books about his writings and how many times his writings have been reprinted and retranslated, it's hundreds of millions of books.

20M+ is the expected sale price
In publishing the big 3 classic authors are
Bibles

Nostradamus
Modern authors sell a fraction compared to those big 3
