A Journey Round My Skull has a terrific post, BLICKFANG: The Eye-Catching Covers of Weimer Berlin, featuring 25 book cover and related designs.
The visual bounty comes from the 2005 (and unfortunately out-of-print) book Blickfang: Bucheinbände und Schutzumschläge Berliner Verlage 1919 – 1933 published by Holstein. The book is packed with over 1000 examples, many from the heavyweights of graphic design of the period.
Would love to see this one reprinted or in an e-version that is faithful to the imagery.
