What first catches the eye is the sheer exuberance of Otto Plattner’s design: a towering, cartoonish animal—part dog, part elephant, with a clown’s nose and a jester’s cap—leans down to meet a poised, masked woman in a rabbit costume. The palette is restricted to a bold duet of red and blue, but every inch pulses with anticipation and playful absurdity. The animal’s exaggerated features, from its wide, startled eyes to its bulbous snout, set the tone for a night where the ordinary rules are suspended.

The woman, striking a confident pose with one hand raised, is both participant and ringmaster, inviting the viewer into the masquerade’s world of fantasy and reversal. The composition draws the gaze from her outstretched arm to the animal’s looming head, then down to the text announcing the event—every element choreographed to heighten the sense of spectacle. Created in 1934, this poster belongs to a vibrant tradition of interwar European graphic art, where artists like Plattner transformed public announcements into visual theatre. Such works were commissioned to advertise the masked balls and society gatherings that offered respite from daily life, especially in cities like Basel with their rich carnival culture.

The playful, almost surreal style echoes the era’s fascination with jazz, cabaret, and the freedoms of modern nightlife, while the precision of the typography and layout reflects the influence of contemporary Swiss design. History has kept few traces of Plattner’s individual commissions, but the energy and wit of this poster speak for a whole world of anticipation and escape—one that still invites the viewer to imagine stepping behind the mask.
