Here's a house ad for Marvel's magazines at the time, which included HOWARD THE DUCK, SAVAGE SWORD OF CONAN, HULK, and DRACULA.
It ran in MARVEL SPOTLIGHT 6, cover-dated May 1980. And in other Marvel titles out the same month.

In the same issue, I love the Marvel subscription ad "What's Wong With This Picture?" Marvel subscripion ad, with a bunch of fun and quirky oddities.
Signed by Ron Zalme, a Marvel production staffer at the time.

With art by Gene Colan / Dave Simons.
Dave Simons, who is now deceased, and as I recall died rather young, did beautiful art on many Marvel stories in the 1979-1992 period, particularly on Marvel magazines, both inking others like John Buscema and Gene Colan, and at other times doing both pencils and inks himself.

Here it is in a much larger size:
