Supergirl in "40th Century Outlaw"
Written by Otto Binder, penciled & inked by Kurt Schaffenberger.
After Linda Danvers journeys to the 40th Century as an exchange student, she learns that Supergirl has been branded an outlaw by history. While getting ready to return to her own time, she finds she must become Supergirl to save innocents, which lands her in prison. As she stands trial, she hopes to avoid conviction with the help of Robin, who was accidently transported to this time period by the Legion of Superheroes.
Note: Lois Lane and Jimmy Olsen turn out to be ventriloquist dummies and Robin is a disguise worn by Mxyzptlk ( who happens to be a 40th century descendant of the original).
