House of Mystery # 158, 1966
While they have paired down the number of sections on the H Dial today, during the first run of the series it seems there were enough letters to spell out hero, heroine and villain which means that Robby Reed had wanted to he could have also dialed up:
airliner, earl, lover, noh, noir, oni, raver, ravioli, alien, and healer.
I don’t know…. say that Little Town were he lived was about to have a dam bust so he dials A I R L I N E R and becomes a 747 and starts flying people out, sockamagee! works for me.
