Kubert served as DC Comics' director of publications from 1967 to 1976. He made the Unknown Soldier the lead feature of "Star Spangled War Stories" with issue #151 (June–July 1970) and initiated titles based on such Edgar Rice Burroughs properties as "Tarzan" and "Korak". Comics historian Les Daniels noted that Kubert's "scripts and artwork ranked among the most authentic and effective ever seen." DC Comics writer and executive Paul Levitz stated in 2010 that "Joe Kubert produced an adaptation that Burroughs aficionados could respect." Kubert supervised the production of the comic books "Sgt. Rock" and "Weird Worlds". While performing supervisory duties he continued to draw for some books, notably "Tarzan" from 1972 to 1975 and drew covers for "Rima the Jungle Girl" from 1974 to 1975. He edited "Limited Collectors' Edition" #C–36 which features stories from the Book of Genesis adapted by writer Sheldon Mayer and artist Nestor Redondo. Kubert and Kanigher created Ragman in the first issue (Aug.–Sept. 1976) of that character's short-lived ongoing series.
