BILL CRIDER'S POP CULTURE MAGAZINE

Of course, by the 1970s, Doubleday was making their books out of paper towels and library paste, and they hired people who were fired from roughing out NANCY comic strips or busted for less impressive graffiti to do original covers for the likes of ROGUE MOON and THE DEMOLISHED MAN...but I was still a happy customer, particularly after moving to Hawaii where they didn't automatically send one anything...
Latter '70s, anyway...the Book Club editions were no better than most of their trade editions.
