I came across a BBC documentary from 1980 about Hieronymus Bosch. There is a scene where the narrator is in his study and we can see the books on his table, I would like to find what the biggest book is on the bottom, ideally ISBN or author's name. Picture below:
It's just the spine of the book, which is not ideal. However we can make out the font and color, which seem rather distinctive. Perhaps someone familiar with the scholarship around Bosch will recognize this book. Also, it would have had to been written before 1980, clearly.
Any help appreciated.
Note: I suffered through the credits of the documentary but there are only special thanks to museums and the collection owners, no mentions of his books.
