Otto Dix was a German painter and printmaker from the early 20th century who was best known for the artwork he created based on his experiences of fighting on the Western Front during World War One.
This image comes from Der Krieg (The War) a selection of sketches he created shortly after the war had finished.
Artist's Notes:
The war provided a windfall for scavengers such as worms and maggots. Trench rats roamed as big as beavers. Gas was sometimes a welcome respite as it decimated these pests.
