He starred in three issues of his own comic, cover-dated September 1966 to February 1967.
[1] Spyman #1 contained the first professional comic book works by Jim Steranko.
Steranko created the concept and plotted the first story, but he did not supply any artwork, except the first page splash which includes a diagram of his robot hand.
Spyman was secret agent Johnny Chance, who lost his left hand defusing a nuclear bomb.
[2] Chance and LIBERTY fought against MIRAGE (Empire of Guerrilla Assassination, Revenge, and International Menace), led by the Whisperer, who was killed in the first issue, and Chance would go on to fight Cyclops and the Evil Eye Society in the second issue and the Id Machine in the third.
