Superman's Girl Friend, Lois Lane #48

Lois turns off a secret recording of Superman just before he reveals his secret identity. In gratitude, Superman offers to take her to three different time eras where they will both live for a time, with him in disguise. If she discovers his identity in any of the other times, he will tell her his modern-day secret identity. For the first test they travel to ancient Troy, where she takes the place of the incomparable beauty Hellene.
