Pictures at an Exhibition presents images of one notable show every weekday. “Daniel Buren: To Align: works in situ 2017” is on view at Bortolami in New York through Saturday, June 24. The solo exhibition is a site-specific commission, which the artist terms in situ, meaning it “denotes a work made for a particular site, for a particular time and exhibited in this particular site, and therefore not transportable to another place,” according to the press release.
