There had been a Yellow Submarine comic published by Gold Key Comics in 1968, produced in advance of the movie. It included passages not found in the film, and character designs made prior to the final designs were okayed for the film. (wogew.blogspot)
In 1968, a comic book based on the movie Yellow Submarine was made. It was published by Gold Key comics. It doesn’t quite follow the storyline of the whole movie, it has seas that are not in the movie such as:
The Sea of Consumer Products
The Sea of Cinema
The Sea of Time looked different
The Sea of Holes looked almost the same
It has songs that are not in the movie such as:
Lovely Rita (from the Sgt Pepper album)
Getting Better (from the Sgt Pepper album)
Mary Had a Little Lamb is not a Beatles song, but it was sung to distract the Blue Meanies (by yellowsubmarine.wikia.com)
So, here´s this comic … a really nice, crazy and funny trip in the golden days of pop art …
