Watchmen

Moore, renowned for many other of the genre's finest creations (Saga of the Swamp Thing, V for Vendetta, and From Hell, with Eddie Campbell) first put out Watchmen in 12 issues for DC in 1986-87. It won a comic award at the time (the 1987 Jack Kirby Comics Industry Awards for Best Writer/Artist combination) and has continued to gather praise since. The story concerns a group called the Crimebusters and a plot to kill and discredit them.
