Comic book writing sure has changed from the Silver Age. In the 50s and 60s, nearly every comic book published was a one-and-done or a two-shot story. There were no sweeping arcs over five, six, seven, or more issues. There was no expectation of collecting issues into trade paperback and hardcovers to be sold as complete stories. Of course, this meant that Silver Age superhero stories seldom had the complexity and depth of their modern-day counterparts, but there is something much more liberating in writing quick, concise adventures. This is why Action Comics #40 is such a breath of fresh air.
