This is a rare find that took me over three years to put together three (!) images from the 6 that were illustrated for the book Névrose.
This book was published in 1921 and illustrated by Gaston Smit.
Since I feel I won't be able to track down the other images I decided to put my findings so far online, and hopefully one day I can add the other three artworks.
