Maybe I'm going insane, but....
Just looking at a few Mandrake the Magician strips and I notice that the art styles of Kurt Shaffenberger and Phil Davis, the artist on Mandrake, are very similar. Especially in these strips I'm looking at, the hands and faces, and some poses, are similar. I wonder, could Kurt have worked on the Mandrake strip during this period (late 50s-early 60s)?
Davis had several ghosts/assistants. He died in 1964 and his assistant Fred Fredericks took over. Kurt was working as a journeyman in the late-50s, after the end of the Marvel family and right before the beginning of his gig at National and Lois lane. He worked for ACG and other publishers. Could he have worked in the strips?
Has anyone read the Kurt bio from TwoMorrows?
