Patrol Total War", "Fantastic Voyage"), Harvey ("Unearthly Spectaculars"), King Comics ("Jungle Jim"), Atlas/Seaboard ("The Destructor"), Youthful Comics ("Capt. Science") and the toy company Wham-O ("Wham-O Giant Comics"). In 1965, Wood, Len Brown, and possibly Larry Ivie created "T.H.U.N.D.E.R. Agents" for Tower Comics. He wrote and drew the 1967 syndicated Christmas comic strip, "Bucky's Christmas Caper". During the 1960s, Wood did many trading cards and humor products for Topps Chewing Gum, including concept roughs for Topps' famed 1962 "Mars Attacks" cards prior to the final art by Bob Powell and Norman Saunders.
