Action Comics, published on April 18, 1938 (cover-dated June),
by National Allied Publications, a corporate predecessor of DC
Comics, is considered to be the first true superhero comic; and
though today Action Comics is a monthly devoted to Superman,
it began, like many early comics, as an anthology.

As of 2011, this is the only comic to have sold for more than $2
million for a single original copy. It is considered to be the most
valuable comic book of all time.

In 1933, salesperson Maxwell Gaines and sales manager Harry 
I. Wildenberg of Eastern Color Printing collaborated with Dell
to publish the 36-page one-shot Famous Funnies: A Carnival of
Comics, considered by historians to be the first true American 
comic book. It was a reprinting of earlier newspaper comic strips,  
thus came the term comic book. These publications established  
the story telling and format that is still used today.
