| Notes | The cover of this book was a part of a contest. Readers could try to identify the artist who drew each character. The reader that guessed the most correctly won an autographed page of Giffen/Mahlstedt art from this issue. The contest winner was David C. Zimmerman of St. Louis, MO. Second-prize winners won a Legion poster. Cover credits are credited as revealed in the letter column for Legion of Super-Heroes #306 (December 1983). |
