Published in October 1963, Fantastic Four #19 is a landmark Silver Age Marvel key featuring the first appearance of Rama-Tut, the time-traveling Pharaoh who was later revealed to be an incarnation of Kang the Conqueror. The CGC label also notes the letter from Steve Gerber and the inclusion of the full page advertisement for X-Men #1, adding further historical interest to this early Marvel issue. Written by Stan Lee with artwork by Jack Kirby and Dick Ayers, and featuring a cover by Jack Kirby and Paul Reinman, this issue exemplifies the creative partnership that defined the Marvel Age of Comics. Professionally graded CGC 4.0 with White Pages, this copy presents as an attractive mid-grade example of an increasingly important key issue. With Rama-Tut's connection to Kang and the Marvel Cinematic Universe continuing to fuel collector interest, Fantastic Four #19 remains one of the more desirable early issues of Marvel's flagship title.
