Action Comics #1 features the first appearance of Superman, a creation of
Jerry Siegel and Joe Shuster. The publication is considered to be both the
genesis of the super-hero genre as well as the most valuable comic book
of all time, with a single original copy selling for more than $2 million in
2011.
