On the first floor, the exhibition at the Galerie Jean-François Cazeau transports visitors into the dreamlike world of the Franco-Chinese painter Zao Wou-Ki, featuring a historic watercolor exhibited at the Galerie La Hune in 1962 (priced at 290,000 euros). Nearby is a signed work by the painter Foujita and a mesmerizing canvas by Japanese artist Yayoi Kusama (950,000 euros).
