Thanks bud!
There is also a DC character Mr. E who is no relation but Ditko first published Mr. A back in 67, a year after he produced the Question for Charlton. While the Question had a much harder edge than other mainstream comics of the time, he was still a toned down version of Mr. A, who tended to kill the criminals he pursued. Although Ditko's been publishing the character ever since, he's kept it in fanzines and small press publications. I suspect it has to do with Ditko's complete distrust of the major publishers. Frank Miller loves the character and even approached Ditko about collaborating on a Mr. A series and still allowing Ditko complete creative control but Ditko turned him down!
This image is strongly based on the events of the back cover of Mr. A #1 ('73), Ditko's first venture into independent publishing, a rather significant event in Ditko's long career (Ditko is STILL putting out new comics in this manner as recently as last year).
There's a great book on Ditko and his art called "Strange and Stranger, the World of Steve Ditko." Check it out, an interesting read of Ditko's story and it's jam packed with great Ditko illustations!
