featured both in anthology books such as All-American Comics and Comic Cavalcade, as well as his own book, Green Lantern. He also appeared in All Star Comics as a member of the superhero team known as the Justice Society of America. After World War II the popularity of superheroes in general declined. The Green Lantern comic book was cancelled with issue #38 (May–June 1949), and All Star Comics #57 (1951) was the character's last Golden Age appearance. When superheroes came back in fashion in later decades, the character Alan Scott was revived, but he was forever marginalized by the new Hal Jordan character who had been created to supplant him (see below). Initially, he made guest appearances in other superheroes' books, but eventually got regular roles in books featuring the Justice Society. He never got another solo series, although he did star in individual stories and in the single-issue 2002 comic book Brightest Day, Blackest Night. Between 1995 and 2003, DC Comics changed Alan Scott's superhero codename to "Sentinel" in order to distinguish him from the newer and more popular science fictional Green Lanterns. In 2011, the Alan Scott character was revamped.

He had a new name, a redesigned costume, and a rewritten origin story. Hal Jordan received his ring from a dying alien and was commissioned as an officer of the Green Lantern Corps, an interstellar law enforcement agency overseen by the Guardians of the Universe. Hal Jordan was introduced in Showcase #22 (September–October 1959). Gil Kane and Sid Greene were the art team most notable on the title in its early years, along with writer John Broome. His initial physical appearance, according to Kane, was patterned after his one-time neighbor, actor Paul Newman. Later developments With issue #76 (April 1970), the series made a radical stylistic departure. Editor Schwartz, in one of the company's earliest efforts to provide more than fantasy, worked with the writer-artist team of Denny O'Neil and Neal Adams to spark
