The Incredible Hulk #140

In "The Brute... That Shouted Love... at the Heart of the Atom!", the Hulk is shrunk to microscopic size and transported to the hidden world of the Psyclops, where he unexpectedly regains Bruce Banner’s intelligence, earns the admiration of its queen, and is set to be betrothed—until the menacing Psyklop arrives to disrupt everything. Written by Harlan Ellison and Roy Thomas, with dynamic art by Sam Grainger and Herb Trimpe, and a striking cover by Trimpe, this 1971 Marvel classic blends surreal sci-fi adventure with the Hulk’s inner struggle, all in a 15-cent comic that remains a standout in the series.
