This week saw many events in the art world. REVOK and POSE made a new work for New York's Bowery Wall, Frank Gehry unveiled designs for three buildings in Toronto, Marilyn Monroe photographer Bert Stern passed away, and The Met decided to do away with its classic tin buttons. On the celebrity side, Marc Jacobs and David Beckham became friends. There was also the big Serpentine Gallery Summer Party which brought in celebs like Sarah Jessica Parker and Naomi Campbell. This one's a scorcher but we hope you'll appreciate our hot compilation of The Best Artist Instagrams of the Week.
