So, when I found out from this post that Mizuki Shigeru of Gegege no Kitarou fame had also done a manga called Gekiga Hitler, I knew I had to see it for myself. Here are a few pages so you get some idea.
I love this one: A Mr. Magoo-ified version of Churchill does the V sign, no doubt the main historical contribution he is remembered for in Japan now.
Mizuki doing The Standard Bearer.
In this last page, the narration tells us that Hitler silently shakes everyone’s hands, goes into his room, and a dull gunshot is heard.
