His cartoons covered a long stretch of history, but here we mainly stress on his cartoons during WW2.....We present his collection of cartoons called "Hitler and his Gang"
Efimov had an abundance of wit and was exceptionally well read, which gave his drawings a stinging conceptual punch. A telling example is a Efimov drawing from World War II described by Vladimir Mochalov, a fellow cartoonist and artistic director of the famous satirical magazine, Krokodil: “Boris Efi mov published a famous cartoon with the caption: ‘A True Aryan is Tall’, and he drew a small, scrawny Goebbels; ‘A True Aryan is Fit’, and he drew a fat Goering; and, ‘A True Aryan is Blond’, for which he drew Hitler with his black bangs. This was an absolutely timely, witty drawing, a classic political cartoon that you might call: aiming straight between the eyes.” In the bleak early years of the war, cartoons like this one played a critical role in maintaining morale. Efimov himself says about those cartoons, “I have an entire folder of letters from frontline soldiers who thanked me for those cartoons, who wrote me, ‘Draw their faces even funnier, because then it’s more fun to pull the trigger.’”
