The annual ABAA New York International Antiquarian Book Fair returns to the Park Avenue Armory for its 65th edition. This year’s fair features over 200 exhibitors with offerings on art, science, literature, history, cooking, and fashion. There are also children’s books and the rarest of first editions. The fair has expanded its annual Ambassador’s Program, which features literary influencers who will be in attendance, a lineup that includes Alexandre Assouline, Emma Roberts, and Sarah Hoover. Exciting items up for grabs include props from the play Sleep No More; never-published J. R. R. Tolkien letters; and a collection of Mao Zedong’s musings on Communism in their earliest editions, expected to fetch $1 million. —Lucy Horowitz
