This is the cover of Newton Comics' The Invincible Iron Man #2:
It originally appeared on the cover of Marvel Comics' Iron Man #4:
The story contents are as follows:
Unconquered is the Unicorn!, originally published in Iron Man #4, August 1968
From the Void Of Space Comes... The Super Skrull! [Part 2], originally published in Marvel's Space-Born Superhero! Captain Marvel #2, June 1968
Unconquered is the Unicorn! appears to have been reprinted complete and intact.
This is the first page of From the Void of Space Comes... The Super Skrull [Part 2]:
In order to accommodate the title the bottom portion of the first tier of panels has been cropped. Compare to a scan of the same page in Page Publications' Captain Marvel #1:
At least the cropping by the Newton editor was a bit more sensitive to readers trying to follow the plot and narration compared to other such instances.
The poster in this issue is The Amazing Spider-Man:
This is a modified version of the cover on Marvel Comics' The Amazing Spider-Man #128, and also appeared as a poster in Daredevil #2. It was later used on the cover of Newton Spectacular: The Amazing Spider-Man.

Prince Namor, The Sub-Mariner #1
The Incredible Hulk #15
This issue includes two letters pages, a Captain America iron-on transfer, and a competition with the inexplicable expiry date 31 January 1976.
