The cover is from Marvel's The Amazing Spider-Man #7:
The story contents are as follows:
The Return of The Vulture, originally published in The Amazing Spider-Man #7, December 1963
The Thunder-God and the Thug!, originally published in Journey into Mystery #89, February 1963
This issue includes a Dracula poster:

Whilst The Amazing Spider-Man #5 realigned the series with its US counterpart in terms of issue number, cover and lead feature, this issue skipped the contents of the US The Amazing Spider-Man #6 and presented the main contents of The Amazing Spider-Man #7. The Mighty Thor backup series was reinstated after a hiatus, but it was not advertised on the cover.

This issue as advertised inhouse:
This advertisement is scanned from The Fantastic Four #4.
The expiry date for the contest is 29 September 1975.

Conan the Barbarian #1 also earns an in-house advertisement stating On Sale Now. However, it was advertised in other Newton comics as on sale 30 August 1975. This suggests Conan the Barbarian #1 was delayed. Dr. Strange may have been similarly affected - TBC.
