Trivia:
The Neal Adams designed costume worn by Robin of Earth-One in this issue could have been a permanent change; readers were asked to write in with their views on the matter. Instead, however, a slightly different version of this look (with a full cape rather than underarm glider wings) was eventually adopted by Robin of Earth-Two in the revived 1970s incarnation of All-Star Comics. Robin of Earth-One retained his original costume until the early 1980s.
