Here's a preview of W's December/January Art Issue cover, featuring George Clooney. After the snapshot above appeared on PopDuJour's Instagram (the proprietor, Ahmad-Ali Swaid, runs a blog by the same name and oversees social media for GARAGE), it was immediately posted to the forums. That was three days ago. No other photographs or scans of the magazine have surfaced on the Internet since.
For the publication's Art Issue, W typically collaborates with contemporary artists on conceptual celebrity covers (one of the most notorious examples: for the November 2010 issue, Kim Kardashian appeared on the cover fully naked except for three strategically placed Barbara Kruger text banners). Although the fashion glossy has not yet released the name of the artist who collaborated with W on Clooney's cover, it is most likely Yayoi Kusama, who is known for her distinctive bright polka dots. The Japanese artist has often incorporated clothing design and runway shows as part of her artistic practice; in 2012 she collaborated on a collection with Louis Vuitton.
