As you can read in the title , Willem Sandberg experimented with typography and designs.
During the occupation by the Germans he published experimental books with his own typography. Mostly a combination of very original and personal lay-out and torn out letters, making these publications unique. Unique because of their chosen size, material, printing ,their design and the very limited numbers in which they were produced.
Sandberg produced nineteen pamphlets between December 1943 and April 1945, making a couple of copies of each one, all done by hand. They consisted of twenty to sixty pages of drawings, collages, and texts, which were either written by Sandberg himself or quoted from Confucius, Proudhon, Stendhal, and other favorite writers on themes like love, death, education, architecture, and typography. As Sandberg had no money and materials were scarce in wartime, he improvised by using whatever he could find: scraps of wallpaper, cardboard packaging, tissue paper, and wrapping paper together with photographs, drawings, and symbols torn from magazines for his collages.
The originals are very very rare and exceptionally hard to find. Luckily some of the dutch publishers decided to make some reprints and make them in this way available for other admirers. These reprints are getting more scarce every year now, but www.ftn-books.com still has some available.
