"Injustice Anywhere Is A Threat To Justice Everywhere"
As far as I can tell, there's no archive of editorial cartoons featuring work that's of the same era as Martin Luther King, Jr.'s life and assassination; I'd love for somebody to do that. I'm intrigued by King's treatment by cartoonists of that time. I'm not sure that Herblock ever drew him, and this is the only Bill Mauldin I'm certain exists. Paul Conrad drew him maybe a half-dozen times. From my cursory reading of editorial cartoons from that era, it seems like a number of cartoonists went for the richer, more damning images of specific events that took place during the Civil Rights movement over depicting the personalities involved.
