In 1968, long-time DC editor Murray Boltinoff took over the editing chores on "Superboy" from Weisinger starting with issue #149. (By this time, "Adventure Comics" was no longer publishing original Superboy stories.) Stories published under his editorial guidance usually included credits, making writers and artists easier to track. Frank Robbins, best known for his work (as both writer and artist) on Batman, began writing the Superboy strip with Boltinoff's debut as editor, and remained the primary scripter for three years. Penciler Bob Brown began one issue later, and continued to pencil Superboy stories through the final Superboy feature in #197. Brown's pencils were inked by a number of artists, most notably Murphy Anderson from 1970 to 1973, who was simultaneously inking Curt Swan's pencils on Superman. After Robbins left, Leo Dorfman returned as the writer for Superboy, with occasional scripts by Bridwell and, toward the end, Cary Bates, later famous for his Superman stories. Boltinoff also made the editorial decision to switch the Legion backup feature from "Action Comics" to "Superboy" in 1971, and later to make the Legion feature the sole feature in the comic.
