The Occult Files of Dr. Spektor #15

Gold Key's occult adventure series delivers a genuinely unsettling cover here, with Dr. Spektor recoiling in alarm before a glowing crystal orb that pulses with the unmistakable form of a living brain — the Brain of Xorkon itself. Looming ominously above the scene, a dark caped figure raises a wooden stake or club in a threatening pose, adding to the supernatural tension that radiates across the burnt-orange composition. Jesse Santos's painted cover work gives the whole image a moody, pulp-horror atmosphere that feels perfectly at home in 1975's rich vein of occult comics storytelling.
