The Adventures of Rex the Wonder Dog #27

In "Mystery of the Midget Sub!", Rex the Wonder Dog proves his mettle on a Western bus tour when he halts a cattle stampede, tracks down a panther responsible for the chaos, and survives quicksand and an avalanche—only to earn a surprising friendship with the wildcat and a heartfelt reward. Written by John Broome and brought to life with dynamic art by Gil Kane (pencils and inks) and Bernard Sachs (inks), this 1956 adventure features Rex’s trademark heroism and a touching twist that lands him a tiny, grateful companion. The cover by Gil Kane captures the moment with playful flair.
