House of Mystery #171

House of Mystery #171 (On Sale: October 5, 1967) has a Dial H for Hero cover by Nick Cardy. This is Nick's only cover this month. In a few years Cardy and Neal Adams will be doing the majority of the DC covers.

"The Micro-Monsters" is the Dial H for H.E.R.O. story written by Dave Wood and drawn by Frank Springer (#170 being Jim Mooney's last). The Doc Morhar's gang breaks into a chemical plant to steal rare chemicals. Robby Reed follows the crooks as King Viking. Robby smashes into their hide-out while Morhar is performing a chemical experiment. An accidental chemical spill causes Robby and the crooks to shrink into a microverse.

Robby encounters a race of sentient microbes bent on dominating the Earth. He tries to enlist Morhar's help in stopping the microbes, but the crook turns on him. Robby, in the super-hero form Go-Go is captured.

Doc Morhar leads the microbes to Earth and explains how to take over the planet.

The back-up feature is "The Martian Marauders" starring the Martian Manhunter and it's by Jack Miller and Joe Certa.
