John Alton is credited in the reprint, but, in an interview from Graphic Story Magazine number 15 (Summer 1973), Harry Harrison said he did this story with Wally Wood.

It is included in Harry Harrison: An Annotated Bibliography, which credits Harrison with the art and tentatively credits him with the script.
