Frank R. Paul's Giant Insectoid Machine, Amazing Stories May 1926

A biomechanical nightmare hovers at center: a winged insect creature with glowing red eyes clutches a transparent egg-shaped glass orb suspended in a gyroscopic metal armature, its spindly red legs poised above a reflective pool. Behind it, a vast alien cityscape of domed buildings nestles beneath crimson mesa cliffs under a deep blue sky. More of the winged creatures dot the horizon. This is the inaugural year of Hugo Gernsback's genre-defining magazine, brimming with the garish optimism of early science fiction.
