Derrick Bostrom writes about the vanishing joy of finding old paperback anthologies of comics and humor magazines at used bookstores and junk shops. He also links to a terrific set of cover scans from his collection.
I remember when I was twelve years old, finding a coverless copy of Kurtzman's "Trump" Number 2 from 1957, for probably no more than a dime (ten comics for a dollar, no doubt). The following year, when I became a Kurtzman fanatic, I was astounded to realize what I had. The same goes for the odd paperbacks I'd pick up during a dull summer vacation day, or inherit from older friends and family. Years later, I'd realize that the poorly printed black and white paperback of sci-fi comic stories was actually reprints from EC's "Weird Science!"
