I recently helped illustrate a funny little history book called "Badass", filled with vulgar language, but quite entertaining and educational. Written by the amazing Ben Thompson.
Here was the illo for Peter the Great, known for his hard drinking as well as his "badassness".
I illustrated this while at the height of my "ink splatter" brush fascination, so they were quite fun to do.
It's published by Harper Collins, so it should be available in most major retail book stores. It's also on Amazon.
