PLANET OF THE APES (1975) Fortress Playset

Here's another great Space: 1970 holiday "wishlist" gift - the Mego Planet Of The Apes Fortress Playset! Who wouldn't have loved to find that under the tree? Personally, I had a couple of the POTA figures, but I never had any of the cool accessories. Usually, I would just concoct backyard scenarios where Captain Kirk somehow ended up on the Ape-dominated world and would get chased by (and fight with) my gorilla soldier.

On a related note, has anyone else ever wondered why Mego (or their ad agency) decided to score most of the Apes toy spots with that weird version of Also sprach Zarathustra...?
