Mickey Mouse Slips on Soap

A pencil sketch from Walt Disney Studios showing Mickey Mouse mid-slip on a bar of soap—a gag rooted in silent-film slapstick tradition. This drawing was produced for *Steamboat Willie*, released in November 1928, the first Mickey Mouse cartoon and the first animated short with synchronized sound. The sketch reveals the studio's working method: careful line work defining the character's articulated limbs and rubber-hose animation style. *Steamboat Willie* established visual conventions that would define animation for decades—clear character design, readable action, and comedic timing calibrated for sound. Mickey's anarchic energy and expressive body language made him an instant star, transforming the mouse from a minor character into cinema's first animated superstar and Disney's foundation.
