any artists do." Eventually Lee & Ditko would take Strange into ever-more-abstract realms. In an epic 17-issue story arc in Strange Tales #130–146 (March 1965 – July 1966), Lee and Ditko introduced the cosmic character Eternity, who personified the universe and was depicted as a silhouette whose outlines are filled with the cosmos. As historian Bradford W. Wright describes, The cartoonist and fine artist Seth in 2003 described Ditko's style as: In addition to Dr. Strange, Ditko in the 1960s also drew comics starring the Hulk and Iron Man. He penciled and inked the final issue of The Incredible Hulk (#6, March 1963), then continued to collaborate with writer-editor Lee on a relaunched Hulk feature in the omnibus Tales to Astonish, beginning with issue #60 (Oct. 1964). Ditko, inked by George Roussos, penciled the feature through #67 (May 1965). Ditko designed the Hulk's primary antagonist, the Leader, in #63 (Jan. 1965). Ditko also penciled the Iron Man feature in Tales of Suspense #47–49 (Nov. 1963 – Jan. 1964), with various inkers. The first of these debuted the initial version of Iron Man's modern red-and-golden armor. Whichever feature he drew, Ditko's idiosyncratic, cleanly detailed, instantly recognizable art style, emphasizing mood and anxiety, found great favor with readers. The character of Spider-Man and his troubled personal life meshed well with Ditko's own interests, which Lee eventually acknowledged by giving the artist plotting credits on the latter part of their 38-issue run. But after four years on the title, Ditko left Marvel; he and Lee had not been on speaking terms for some time, with art and editorial changes handled through intermediaries. The details of the rift remain uncertain, even to Lee, who confessed in 2003, "I never really knew Steve on a personal level." Ditko later claimed it was Lee who broke off contact and disputed the long-held belief that the disagreement was over the true identity of the Green Goblin: "Stan never knew what he was getting in my Spider-Man stories and covers until after [production manager] Sol Brodsky took the material from me ... so there couldn't have been any disagreement or agreement, no exchanges ... no problems between us concerning the Green Goblin or anything else from before issue #25 to my final issues". Spider-Man successor artist John Romita, in a 2010 deposition, recalled that Lee and Ditko "ended up not being able to work together because they disagreed
