In The Days of the Mob #1 Cover Rough by Jack Kirby

This was just run in the latest issue of The Jack Kirby Collector(#49)--Jack's cover rough for In The Days of the Mob #1. One of the reasons I subscribe to JKC is that they manage to find this amazing stuff.

As you can see, he had most of it pretty well done in his head(no surprise there; this is Jack Kirby we're talking about here), and the finished cover looked pretty close to this--the one exception being the old-timey "Comics" tag at the end of the title, eventually dropped.
