Star Trek #35

This 1975 Gold Key issue puts Mr. Spock front and center in genuinely unsettling fashion — his enlarged, stern face dominates the cover while ghostly, luminous alien forms swirl and surge outward from his mind, with a small photo inset of Spock and Kirk anchoring the crew's human (and Vulcan) stakes. The cover copy spells out the threat directly: an alien form invades the Enterprise through Spock's very consciousness, making this a compelling setup for "The Creatures of Light." George Wilson's painted cover work gives the whole thing an eerie, almost psychedelic energy that perfectly suits a tale of mental invasion aboard the Federation's most famous starship.
