Edison's Conquest of Mars: Man with Disruptor Device Illustration

This illustration is from Garrett P. Serviss's 1898 pulp serial Edison's Conquest of Mars, not H.G. Wells' The Invisible Man. The scene depicts a man in a rugged, rocky or architectural setting holding a device, likely one of the futuristic weapons or tools featured in Serviss's tale of interplanetary war and Earth's counterattack against Martian invaders. The cross-hatched pen-and-ink style is typical of period newspaper syndication illustrations accompanying the original serialized text.
