Batman #3

In "The Strange Case of the Diabolical Puppet Master," Batman faces his most unnerving foe yet—a master manipulator who uses hypnotic control to turn the city's citizens into his puppets. Written by Bill Finger and illustrated by Bob Kane, with inks by Jerry Robinson and George Roussos, this 1940 classic sees the Dark Knight battling both a cunning criminal and his own compromised mind, all while protecting the Army's secret weapon, the Voss Rifle. The cover, penciled by Bob Kane and inked by Jerry Robinson, captures the eerie tension of a man in control of another's will.
