The Avengers #141

In "The Phantom Empire!", the Avengers face a web of corporate espionage and time-traveling threats as Beast is ambushed by high-tech assailants and rescued by Captain America, who traces the attack to Roxxon and the mysterious Brand Corporation. With Hawkeye captured by Kang and Thor and Moondragon blocked in a temporal pursuit, the remaining Avengers launch a desperate infiltration of Brand’s base—only to be overwhelmed and taken prisoner by the powerful Squadron Supreme. Written by Steve Englehart and illustrated with dynamic precision by George Pérez, with inks by Vinnie Colletta and colors by Janice Cohen, this 1975 issue features a striking cover by Gil Kane and John Romita.
