The Arrow reveals his true identity to Jane in the story.
Rather unusual for this time period in comics, Carnov refers to his aide as an "ass".
As far as can be determined, this was the Rainbow's only appearance (Craig Delich, 2011-4-18).
Interesting note: if one spells the names of the two colleges running in the relays backwards, you have: "Harvard" (Dravrah) and "Yale" (Elay).
Dash Dartwell was introduced in Amazing Man Comics #21, by-lined Harry Francis Campbell (who drew the feature in 1941). The story line is primarily the same (Bettie is called Lois, and the athletes are not kidnapped....instead their bus is hit, injuring most of the team) but with entirely different art with caption revisions. Also, the last panel is signed "Taylor", which refers to Henry Taylor, who drew Dash Dartwell circa 1941-circa 1942. My guess is that the story in Amazing Man #21 was drawn by Taylor while the story here is Arrow #3 was by Campbell.
All stories in #1 and #2 are taken from DC's inventory.
