Newton Comics' Planet of the Apes #10 is cover-dated October 1975:
The cover image originally appeared on Marvel's Planet of the Apes #10.
The contents are as follows:
Beneath the Planet of the Apes [Part Two: Enslaved!], originally published in Planet of the Apes #7.
The first 7 pages of this story were published in Newton's Planet of the Apes #9. This print omits the opening panel on the first page in order to include the advisory note "continuing the epic marvel adventure BENEATH THE PLANET OF THE APES!":
The missing panel is on page 58 of Marvel's Planet of the Apes #7.
Beneath the Planet of the Apes Part II [Part III]: The Warhead Messiah, originally published in Planet of the Apes #8.
Only the first 12 of 21 pages are reprinted in this issue. The story continues in Planet of the Apes #11. Having neglected to print the full and accurate title in the previous chapter, Newton deemed The Warhead Messiah to be Part 2 of Beneath the Planet of the Apes:
It is in fact Part 3. This would have a flow on effect in subsequent issues.
The poster in this issue is an edited print of the cover of Newton's Dracula #1. The swap card has the cover of Newton's The Amazing Spider-Man #7, and is numbered Series A (1 of 15) No. 7.
The contest expires 1 December 1975.
