Tom Tully is one the most prolific writers ever to grace British comics. His diverse portfolio of work was produced over four decades. Born in Glasgow, Tully entered the industry in the sixties when he began working for Fleetway. One of his earliest strips, Heros the Spartan, ran in the original Eagle and was illustrated by the great Frank Bellamy. He also wrote Mytek the Mighty (Valiant & Vulcan) and The Steel Claw (Valiant & Vulcan) in the same decade. The seventies saw Tully work on a variety of significant stories including Adam Eterno (Thunder), Johnny Red (Battle), Harlem He-roes (2000 AD), The Leopard from Lime Street (Buster) and Roy of the Rovers (Tiger), the strip he worked on longer than any other writer. Jesús Blasco is considered one of the most significant artists in Spanish comics. He created Cuto for Boliche magazine and produced several science fiction and adventure titles.

In the 1960s he joined the British publishing agency Fleetway and worked on Steel Claw, Billy the Kid and Buffalo Bill amongst others. For 2000 AD he provided the art for several episodes of Invasion!.
