I bought this the first time from Eclipse, Steed And Mrs Peel based on the sixties and seventies Avengers TV show, written by Grant Morrison and drawn by The Ballad of Halo Jones' Ian Gibson. A three issue prestige format comic. It was all right, nothing too special, and I remember enjoying Grant's other work at the time, such as Animal Man and Doom Patrol, far more.
