The poster captures a cheeky moment from 1955 Germany featuring 13-year-old Princess Yvonne Sayn-Wittgenstein-Sayn and her brother, Prince Alexander. Yvonne playfully holds a sake bottle, exuding mischief, while Alexander confidently holds their mother's cigarette. The vintage photo, taken by Princess Marianne Sayn-Wittgenstein-Sayn, reflects the siblings' playful rebellion against adulthood. Adding to the whimsy, the poster includes cartoon characters: Tweety Bird lounges, Bart Simpson holds a bottle, using money as a phone. Alexander's glass features flowers and a radiant smiley face, complementing his spirited persona, accentuated by a "stay young" tattoo on his hand. Yvonne, adorned with a flower in her hair, embodies youthful charm amidst their amusing escapade into grown-up antics.
