Who’s on Third?, by Llyn Foulkes, 1971–73. Part of the artist’s retrospective, Llyn Foulkes, at the New Museum. Opens today, on the Lower East Side. This is a bangin’ show, people. Go see it. And listen to my NPR profile of Foulkes while you’re at it. Or, better yet, if you want to see the artist in person, he is giving a talk on Thursday at 7:30pm.  (Courtesy John Jones Collection and the New Museum.)
