On Feb. 23, auction house Christie’s International will begin a three-day sale of up to $425 million worth of art collected by the late fashion designer Yves Saint Laurent and his partner, industrialist Pierre Bergé. The sale of nearly 700 artworks — from Roman antiquities to paintings by Mondrian and Picasso — will feature a celebrity-studded red carpet, $400 souvenir catalogs and a 44,291 square-foot salesroom built into the Grand Palais, Paris’s glass-domed exposition hall near the Champs-Elysées.

Concurrently, YSL has put out what they are branding as the MANIFESTO, which is actually an oversized glossy catalogue of the Spring/Summer 2009 collection. A defunct ground floor retail space has become host to this special New York presentation called Edition Unisex from Feb 12 – Feb 21 at 55 Great Jones Ave @ Bowery.
