The November 2017 vitrine theme: FAIRGROUND IN THE WINDOWS For this new, festive season, young and old will be literally whisked away by the world of an early 20th Century Paris fairground, reconstructed in the windows of Galeries Lafayette Haussmann. The barrel organ draws you in with its catchy rhythm, whilst you follow the feverish race between Pierre, the hero pigeon, and his sweetheart, Coco the gentle dove. In this exaggerated Paris, where a certain 20s surrealism collides with a baroque art deco spirit, a ferris wheel, claw machine, roller coasters…your head will be spinning, but fortunately at the end of the journey they find each other in the sky above Paris. Exactly above the Dome at Galeries Lafayette.
