After the Legion pushed new Superboy stories out of Adventure Comics in 1963, Superboy became the only comic book to feature original Superboy stories. Less than two years after the Legion itself left Adventure Comics, Superboy became the Legion’s new home. Starting with Superboy #172 (March 1971), the Legion appeared as an occasional backup feature. Once again, the Legion feature proved so popular that by Superboy #197 (Sept. 1973), the Legion had become the lead feature, and with the next issue, the title’s only feature. Although from issue #197, the cover logo read Superboy starring the Legion of Super-Heroes (and replaced starring with #222), the official title (shown in the indicia) of the comic remained Superboy until #231 (Sept. 1977), when the comic became Superboy and the Legion of Super-Heroes. In issue #259 (Jan. 1980).
