My source for artist ID? the main one is the eyeballs ---
that and studying artists styles....
sometimes its easy... like Bill Williams - his Dennis the Meance and The Bible Kids #7 looks just like the other Dennis material he was doing...
Oh, heres a story told back in 1981, Marvel's editorial staff knew they had gotten the rights to do the Dennis book, when Bill Williams came in to pick up his asignment from them. No idea if this is really true, its just what was reported back in 81....
My notes indicate Williams started with either issue 119 or 120 (1972)
He had been working for Gold Key prior to that, He did Dennis to the end (except for 146), As far as I know he never signed any of his Dennis work (his signature is on his Marvel and Dell work).
Owen Fitzgerald was working for DC prior to taking over Dennis with #47 (December 1960). - if you have #61, you'll see his name as the rider of a horse (hope I have the story right), he left in 1972, to be replaced by Williams. I know Fitzgerald did a story or so for Marvel around that time (inked by Scott Shaw! so you wont be able to see his inking style!) He did "Goes to Camp". While Fitzgerald was working for DC and Marvel, he was living in California. Mark Evanier first mentioned OF as a Dennis artist to me, back in the late 1970s, but we didnt have the same comics back then, so I had to link OF's style to Dennis books -- I recall when I found this out, having a huge lightbulb go off - saying "wow, he did alot didnt he". This came up in the pages of CAPA-alpha and some other fanzines of the time.
Frank Hill did
Dennis in the middle 1960s-middle 70s, the story in 146 has his name on it.but youll find most of his stories in the bonus magazine series.
as for Wiseman at Dell, I recall folks talking about this in the 1980s-1990s, and I misidentified a few too - but as far as I can see (and I havent seen them all) ALL of the Dell material was actually by Lynn Karp (whose name is on a Wisemen cover)
