From 1975: A text-heavy behind-the-scenes article from MARVEL UK's PLANET OF THE APES weekly issue 43 (cover-dated 16 August 1975).
I'd guess this was ported across from one of the issues of the US black & white POTA magazine, which was pitched at a slightly older audience than the UK weekly (although the contents were fairly identical).
It's hard to imagine that any British publication aimed at younger readers would ever contemplate running something like this today... it would be much shorter and much more superficial.
