Batman
The first Batman story, "The Case of the Chemical Syndicate", was published in "Detective Comics" #27 (May 1939). Finger said, "Batman was originally written in the style of the pulps", and this influence was evident with Batman showing little remorse over killing or maiming criminals. Batman proved a hit character, and he received his own solo title in 1940 while continuing to star in "Detective Comics". By that time, Detective Comics was the top-selling and most influential publisher in the industry; Batman and the company's other major hero, Superman, were the cornerstones of the company's success. The two characters were featured side-by-side as the stars of "World's Finest Comics", which was originally titled "World's Best Comics" when it debuted in fall 1940. Creators including Jerry Robinson and Dick Sprang also worked on the strips during this period.
Batman: Hush
"Batman: Hush" was published in monthly installments within the comic book series "Batman", running from issue #608–619 (December 2002–November 2003) by DC Comics. The first issue of the story arc was a success ranking 1st in the Top 300 comics for the October 2002 period with pre-order sales of 113,061. It was later collected into two volumes as hardcover and softcover, and later in 2005 in an oversized "Absolute Batman: Hush" hardcover slipcase. DC Comics released the story arc in one volume in August 2009. A hardcover collected edition featuring Jim Lee's artwork entirely in pencil form, titled "Batman: Hush Unwrapped Deluxe Edition", was released on February 22, 2011.
