October 1965 - June 1972
10 issues were published of Cracked's 'For Monsters Only'.
Some may quibble as to why this series is included as a Cracked title. Well, for one thing, it says "Cracked" up top on almost all of the issues. More importantly, material from these issues later provided the basis of the "Monsters" issues of Cracked Collectors' Edition and the later Cracked Monster Party with much reprinted material from For Monsters Only there.
