A comic book can be considered a key for many reasons, notably if it has a first appearance. Those character introductions are incredibly important, however, keys can have many other significant firsts. Things like the first teenage comic, first western comic, or first comic with a villain cover can make an issue special.

In The Overstreet Comic Book Price Guide #26, Robert M. Overstreet paid special attention to those and other milestones in the article “Historic Firsts.” Over the last month, Scoop has reprinted that list for our “Inside the Guide” column. Here we present the fourth and final installment.
