Wow! What a mustached bookbinder! I just posted some images of decorated initials from Het drukkers jaarboek 1906 recently, but there is much more interesting in this series of books. And amazing book industry ads is one of these things.
Between 1906 and 1911 four yearbooks about printing were published in Amsterdam. They were intended to stimulate a broader and more logical interpretation of the art of printing.
What I love about international exhibitions catalogs, is the diversity of art. All the works from different artists coming from multiple countries. And that's exactly what you get with the tenth-anniversary celebration of the Belgian Association of Ex Libris Collectors.
