Superman #127 1997

Superman #127, published by DC in February 1959, features three stories, most notably 'Titano the Super-Ape!'. In this key issue, Lois Lane encounters Toto, a chimp launched into space. Exposed to colliding kryptonite and uranium meteors, Toto transforms into the giant, kryptonite-eyed Titano. This marks the first appearance and origin of Titano the Super-Ape, a significant moment for collectors as Superman confronts the colossal primate.
