Giordano wouldn't be considered a Legion artist, but like I mentioned he did ink the covers of many issues starting in the late 1970s. According to the Grand Comics Database, he did over 30 Legion covers (pencils and/or inks).
- His first work was inking Neal Adams for a pinup of the Legion as a group, for the 1976 DC Calendar (that was later reprinted on the Tempo paperback).
- He inked the lead story in "Superboy & the LSH" #246, pencils by Joe Staton, that took place on Mercury
- Inks on S&LSH issues 247-258 in 1979 over Joe Staton and his own pencils
- Issues 259-276 (minus a handful) of "LSH v2", from 1980-81 (over his own, Jimmy Janes, and Rich Buckler pencils). He contributed Saturn Girl to the jam cover of issue 300 in 1983 and inked the "Dark Man" episode in that issue
- Inks on "Secrets of the LSH" in 1981 on issue 1 over Janes and issues 2 and 3 over his own
- Then he returned in 1982 for the LSH Annual 1 cover featuring Computo (over Giffen), "Tales" 314 in 1984 (inking over Larry Mahlstedt, who was normally Giffen's inker), 348 (over Ron Frenz), and 351 (over Curt Swan), both in 1987.
- His last Legion work was in 1988 in "Who's Who in the LSH" 2, where he inked a few pages of Steve Lightle in the history of the Legion timeline at the front, and LSH v3 45 where he pencilled two pages (inks by Mike DeCarlo).
