As per Klaus Biesenbach, MoMA PS1’s director, the New York Art Book Fair had over 10,000 visitors on Sunday alone. It certainly felt like it. This year’s fair, presented by Printed Matter, opened with a performance by Thurston Moore and closed with a show by Gang Gang Dance. It was an epic event that had some visitors, including the Observer’s Nate Freeman, comparing it to Coachella, replete with novelty T-shirts featuring art world royalty, loads of colorful and affordable artworks and artisanal objects that had people advertising their “haul,” and plenty of room to just hang and listen to music, whether outdoors on the steps of the museum or within the special project rooms (well, at least one). Here are some of the wacky things that we saw (or that others saw and posted on Instagram).
