Rosenberger continued with romance work for DC in comic books such as "Falling in Love", "Girls' Love Stories", "Girls' Romances", "Secret Hearts", and "Young Romance", but the genre's popularity was quickly waning. Around 1972–1974, Rosenberger was regularly working on various features for DC titles such as "Strange Sports Stories", "The Superman Family", "Wonder Woman", and "World's Finest Comics", and with such characters as Zatanna and Lois Lane. He and Robert Kanigher co-created Lady Cop in 1975. That character appeared in the fourth season of the "Arrow" TV series in 2015 and was portrayed by Rutina Wesley.
