The girl on the cover of Jungle Comics #85 does not look at all Doolinesqe to me. And no artist is credited at GCD. Thus, I’ve provided no artist credit in the file name.
Jungle Tales #88 is another cover that definitely looks like it is by someone other than Joe Doolin. GCD credits the cover to Ruben Moreira, and since I have no way of confirming or denying their information, I’m just going to take it as fact — although I must say, whoever the artist is, he seems to be trying very hard here to channel Frazetta.
