House of Mystery #131

This 1963 DC anthology delivers a genuinely unsettling cover by Mort Meskin and George Roussos: a massive, snarling creature composed entirely of roiling flames erupts from the earth, engulfing a helpless figure in white while horrified onlookers — including a figure in fringed frontier clothing — watch from below. The story title "Vengeance of the Geyser God!" blazes across the scene, and the desperate caption "Such is the fate of all who anger the fire spirits!" sets a wonderfully ominous tone. House of Mystery was reliably delivering this kind of imaginative, larger-than-life supernatural drama in 1963, and this fiery cover is a strong example of why the series had such a devoted readership.
