This is the 1991 'Love' poster by Yves Saint Laurent, part of his celebrated annual New Year series.
This version is particularly personal, featuring multiple photographic images of Moujik – his French bulldog – rendered in bold, pop-art colour treatments that nod to Andy Warhol. The handwritten French text ('Lui c’est Moujik, mon chien… peint par Andy Warhol… Moi je suis Yves Saint Laurent') adds a playful, self-referential tone, blending humour, art history, and autobiography.
