PLANET OF THE APES 80s VHS Collection Poster

I thought this was a cool piece of Planet Of The Apes artwork - an 80s video store poster advertising Playhouse Video's 5-cassette box set of the Apes features. Considering the cost of most studio pre-record VHS tapes of the era, I bet that set cost a pretty penny. I have no idea who the artist was, but he made some odd choices. First, there's that weird expression on Ceasar's face -- and what's with Taylor's hairline?
