Ploog's art got better and better as the series went on. I think he kind of gave the Gorillas bangs in the first couple of issues.
Issue #8 was one the highlights of his POTA work for me. He totally had the specific look of the ape makeup and costumes down by that point. Also I think they printed the art directly from Ploog's pencil art with out it being inked. Almost unheard of back then, but it came out looking awesome. It had beautiful texture.
The closest I'll get to revist the Planet of the Apes these days is if I can find time to make myself a Gorilla costume for Halloween this year. I have one of the pull over masks from Apemania and I've been meaning to make myself a Gorilla soldier costume to go with it for the longest time.
We'll see.
