Superman vol.1 #31 - Cover date November-December 1944
Luthor’s been a rare sight in this book lately, but he returns with the power of SOUND (i.e. super-destructive tuning forks) now added to his arsenal of anti-Superman weapons.
Lois continues to appear in her slate of stand-alone, shorter features which bear some resemblance to the comic strip in their lightly comic touch (although she gets to do her fair share of actual investigative reporting), and a final story in this volume involves Superman assisting a natural history museum with its attempts to build a valuable stock of displays in spite of efforts at sabotage.
Most interesting story in this volume, however, involves a tale told from the perspective of Lois Lane’s heretofore unseen pooch Flip - the only creature on Earth to know Superman’s dual identity! We all change our clothes in front of the dog, I suppose. Regaling his pup pals with the story of his derring-do alongside the Man of Steel, Flip’s story is another example of the book’s attempts to find new and curious perspectives from which to tell the ‘same old’ crimefighting stories which are its current bread and butter.
