Het Vlas is a text by Hans Christiaan Andersen. Bart van der Leck started to work on this project in 1941. He made several studies before the final version was printed. These final designs are now in the collection of the Kröller-Müller Museum, Otterlo.
Bart van der Leck illustrated the work and did the lay out, using his own letter-type, making each page an exciting typographic composition.
To be sold with the facsimile print of the book, published by Bert Bakker in 1975.
