NEW YORK, NY.- 55 works that reflect the current trends in the art world, are live for bidding on artnet Auctions now through October 27. Featured artists include Ai Weiwei, Tracey Emin, Peter Halley, Jeff Koons, Yoko Ono, Sam Falls, Marilyn Minter, Richard Prince, Chuck Close, Theaster Gates, Guillermo Kuitca, Mickalene Thomas, and more.

Ai Weiwei's Bicycle, one of the highlights of the sale, is a limited edition created to support the Brooklyn Museum's presentation of the major 2014 exhibition, Ai Weiwei: According to What?. The bicycle is stamped on the head tube with a signature and edition number, includes an imprint of an image of the artist's face on the seat, is accompanied by a signed and numbered certificate of authenticity, and is available to view by appointment at artnet's New York City office.

Also, included in the sale is Richard Prince's Untitled (50 Tweets), created in the same vein as Prince's infamous New Portraits series which consists of a set of 50 inkjet prints that show screenshots of the artist's Twitter account, with tweets dating between late 2013 and early 2014. Famous for appropriation, Richard Prince creates art that relies heavily on the work of others and is widely recognized for his photographing of advertisements, and often manipulates images from consumer culture.

Inside Out, Au Panthéon, Nave, Paris, France, by French photographer and graffiti artist JR, captures the artist’s installation Au Panthéon! which opened in June 2014 and covered the floor, dome, and cupola of the Pantheon with images submitted by previous visitors. Covering urban landscapes with his work, JR calls himself an "Urban Artivist" engaging the surrounding community not only in experiencing art first hand, but also helping him put up the portraits where they live.
