That Newt Alfred credit was given to me by Hames Ware, Jedifish,
He and I believe that it is NEVER safe to apply blanket credits to a run from an ID for a single issue. If you look at other issues and they are the same artist, then perhaps those other issues can be credited to Alfred.
As for Kenneth Kennedy, as far as The Who's Who is/was concerned, there was not a real person with that name in comics. "He" should not be considered the creator or the writer. A "byline" is all that can be given to "him".
