As the summer winds down, so do many of the city’s blockbuster museum exhibitions. This year is no different, with the Met’s Costume Institute show “Camp: Notes on Fashion” closing Sept. 8 and the 2019 Whitney Biennial running through Sept. 22. At the New-York Historical Society, a pair of exhibitions commemorating the 50th anniversary of the Stonewall uprising close Sept. 22, and “Life: Six Women Photographers” ends its run on Oct. 6.

But some recently opened surveys will be on view for longer: at the Brooklyn Museum, “Pierre Cardin: Future Fashion” is open through Jan. 5, and at the Guggenheim, there are exhibitions examining the works of Jean-Michel Basquiat (through Nov. 6) and Robert Mapplethorpe (through next summer). The Museum of the City of New York has a pair of companion exhibitions highlighting the works of the photographer Fred W. McDarrah: “The Voice of the Village” is on through Dec. 1, and “Pride: Photographs of Stonewall and Beyond” closes Dec. 31.

And another show at the Museum of the City of New York is particularly pertinent this Labor Day: “City of Workers, City of Struggle,” which highlights the 200-year history of how labor movements shaped New York. (The museum will cut its admission 50 percent from Sept. 1-7 for visitors with a union card.) On view through Jan. 5, the show charts the evolution of the continuing fight for workers’ rights, beginning with the dawn of unions in the 19th century, when discontent among laborers over the changing realities of their workplaces prompted them to agitate for better pay and working conditions, according to the show’s curator, Steven H. Jaffe.
