Limited Collectors' Edition C-49 (Oct/Nov 76) was yet another issue that I really loved. It reprinted the two issue story from Adventure Comics that introduced Mordru, one of the Legion's greatest enemies. Mike Grell does the cover of the issue.
Between the two reprinted issues there is a map of the Legion headquarters, and a few pages with panels from various stories that show the different locations in use. As well, the centre spread reprints the wedding of Bouncing Boy and Duo Damsel, with the huge guest list that includes the Legion, Legion of Substitute Heroes, honourary members, the Wanderers, Tornado Twins and others, all of whom are labelled on the inside back cover.
