This is Mego's 8" Dr. Zaius. He was first released in 1974, also.
Dr. Zaius sort of presides over the science and religion aspects of Ape Society as the "Minister of Science" and "Chief Defender of the Faith." He's seen as a wise old sage by most of ape society. However, Zaius knows more about ape history than he is willing to divulge to others. He's fearful for ape society if the truth of its origin leaks out. Kind of like how our government hides the truth about UFOs, Bigfoot, and Unicorns from us...allegedly, of course. If they do, it's for our own good.
Mego did an outstanding job with the head sculpt on Zaius. It looks a great deal like the character in the films and seems to almost have every crease and wrinkle. He even seems to have that certain twinkle in his eye that actor, Maurice Evans, brought to the role. Am I seeing too much?
Dr. Zaius didn't come with any accessories. It would have been nice if he had come with a scroll or something, though. Nope, he'll just have to suppress the truth and torment humans using only his wits and hairy mitts.
A complete Dr. Zaius should include his fur-cuffed tunic, pants, and black boots. Some versions of Dr. Zaius include boots with symbols from the Ape alphabet embossed on the sides of them. However, the example pictured is wearing the standard black boots without symbols. It should also be noted that with all the Mego Apes, Zaius included, the hands of the figure should be sculpted with a hairy texture.
