Superman #16/1968

In "Rätsel des lebenden Wirbelwinds," Jimmy Olsen takes on a fraudster only to accidentally inhale a mysterious gas, leaving him temporarily blind. During his ordeal, he encounters Supergirl—though he refuses to believe in her existence, despite her earnest attempts to prove herself. Written by Otto Binder and illustrated by Curt Swan with inks by John Forte, this 1968 tale blends suspense and wonder in a story where perception and trust are put to the test.
