Through a contract with the U.S. Holocaust Memorial Museum I developed the maps to be used in War, Pacification, and Mass Murder, 1939: The Einsatzgruppen in Poland. It was a long process working with several researchers to get aesthetics and accuracy correct. I ended up using Photoshop and Illustrator for much of the process. I don't have access to the originals anymore, but feel free to pick up you own copy here.
