(Find me at 50 Watts Books.)

Grosz needs no introduction, but I did find this fun quote in his wikipedia entry:

My drawings expressed my despair, hate and disillusionment. I drew drunkards; puking men; men with clenched fists cursing at the moon. . . . I drew a man, face filled with fright, washing blood from his hands. . . . I drew lonely little men fleeing madly through empty streets. I drew a cross-section of tenement house: through one window could be seen a man attacking his wife; through another, two people making love; from a third hung a suicide with body covered by swarming flies. I drew soldiers without noses; war cripples with crustacean-like steel arms; two medical soldiers putting a violent infantryman into a strait-jacket made of a horse blanket. . . I drew a skeleton dressed as a recruit being examined for military duty. I also wrote poetry.

I scanned most of these from Blickfang, an impossible-to-find collection of German book covers I featured once before.
