Rip Hunter... Time Master #13

Rip Hunter and his companions find themselves in serious trouble on this April 1963 cover, confronted in the court of Kublai Khan himself while a robed figure — identified by cover dialogue as Marco Polo — denounces them as intruders. Bill Ely's linework captures the tension beautifully, with guards closing in on the time travelers as the great Khan gestures in accusation. "The Menace of the Mongol Magician" promises a time-trip to ancient China that puts Rip and his friends squarely in the crosshairs of history.
