Monsters To Laugh With was Marvel Comics' first attempt at a monster-themed (humor) magazine. The format here was basically photo stills from horror films, with funny captions and/or dialogue pasted over them, basically one-page fumetti gags.
The format was enjoyed by little kids, and apparently that was enough to keep it going for several issues.
This magazine would be retitled Monsters Unlimited with #4, for some reason. The format was tried again with Monster Madness a decade later. A 'straight' monster-fan magazine was attempted by Marvel in the form of Monsters of the Movies.
