Giant Mutant Rat Rides Monstrous Crustacean — Robida Pen-and-Ink c.1902

Rendered in scratchy, kinetic pen-and-ink lines, a grotesque whiskered rat-creature perches atop an enormous segmented crustacean — part lobster, part nightmare — its clawed legs splayed in furious motion. The monochrome linework crackles with frenetic energy, the creature's beady eyes and bristling whiskers conveying feral menace. A small 'AR' monogram signature is visible in the lower left, consistent with Albert Robida's distinctive illustrative hand, suggesting this depicts oversized vermin from a speculative or satirical science fiction text circa 1902.
