The Incredible Hulk #198

In "The Shangri-La Syndrome!", the Hulk finds himself trapped aboard The Collector’s cosmic museum, where alien and mutant specimens are locked behind glass—each a prisoner of curiosity. With the promise of a cure for his own rage, the Hulk must decide whether to fight for freedom or surrender to the tantalizing offer. Written by Len Wein and illustrated by Sal Buscema, with inks by Joe Staton and colors by Glynis Wein, this 1976 classic features a striking cover by Gil Kane and John Romita.
