"Bully Beef" is a Terrytoon with World War I theme, released on 13th July, 1930. It's a rather entertaining and fast paced cartoon, among studio's best entries of that year. The drawing style and character design still has its roots in the silent cartoons of the 20s, though with more elaborate animation.
This cartoon is particularly notorious for featuring a couple of the most shocking and gruesome scenes ever seen in a classic cartoon. The old TV prints of this cartoon were probably heavily edited, and these screenshots are taken from an excellent uncut French theatrical print from 1930. In any case, the title of "disturbing cartoon" is fully deserved.
