The Silve Age Green Lantern v.1

DC Comics bought the Flash back as a new character in 1956.  This was a big hit, and they then immediately brought the Green Lantern back as a new character... in 1959.  There were a lot of other tryouts in Showcase Comics, which were probably ready to go before they decided on the basis for Hal Jordan.  Instead of the magical Lantern from the 40s, this Green Lantern was part of the Lensmen Patrol Green Lantern Corps, an interstellar police unit.  They are sent on missions by the Guardians of the Universe, based on OA.  Each of the 3600 members makes use of a power battery, mostly in the form of a ring, that harnesses the use of the bearer's will.  It has one weakness, the color yellow.  This is due to a necessary impurity in the main battery on OA.  Hal Jordan meets his other Lanterns, and joins the JLA and has a lot of adventures.

This book publishes the first 12 books, three from Showcase and 1-9 of Green Lantern.  Drawn by the incomparable Gil Kane, the stories are generally imaginative.  Hal meets other Lanterns, both good and bad, villains, spies and gangsters.  He also meets Tom Kalmaku, who knows his secret ID.

All the comic book tropes are present though, including the "I am my own rival" for the woman I love.  GL is presented as a ladies man, though Hal really is not.  There have been many retcons about the Lanterns, including adding all the colors of the rainbow, probably including plaid.

Hal is my favorite Green Lantern.  How they screwed up the movie is beyond me.
