John Alton is credited in this reprint, but, in an interview from Graphic Story Magazine number 15 (Summer 1973), Harry Harrison said he did this story with Wally Wood. Most online sources don't credit Wood with doing anything in this particular story (though Harrison and Wood did a lot of work together). It is included in Harry Harrison: An Annotated Bibliography, which credits Harrison with the art and tentatively credits him with the script.
Text story with illustrated title.
This is the only editorial comment signed by Chris Rock, who otherwise worked anonymously on the Russ Cochran/Gemstone EC reprints, principally on the letters pages. In an e-mail (30 Aug 2016) to Chris Boyko (myself), he made his case for credit on the reprints. Unfortunately, he mis-remembered the nom de plume he used as "Ed Rock" (I do not actually know his real name) and I did not have this issue of War Against Crime at the time, so I entered his name as "Ed Rock" in all of the Russ Cochran/Gemstone reprints I edited. This needs to be fixed but that will take time, as there are so many entries.
