/the EC comics were highly collectible by the early 60s, when we used to go in and buy 20 used comics for a dollar. I recall Weird Science and Weird Fantasy shrank to the aptly named 'Weird Science-Fantasy' and they all contain a wealth of SF, time-travel, ET you-name-it stories, really good stuff, but the second-hand comic racks were devoid of these titles by 1965, collectors grabbed them all, the buggers, and we were stuck with things like, oh, Amazing Fantasy #15, some spider-guy origin issue, which I had two of till Mom threw them away. Really. You could grab spidey#1, and FF and Hulk#1, but not the good SF titles. Oh for a real time machine...
