The Piccirilli Brothers were a family of stone carvers and sculptors whose marble sculptures included the lions in front of the New York Public Library's Stephen A. Schwarzman Building. The Piccirilli family papers include photographs of the family, their studio, and sculptures; letters; clippings; and ephemera. Among the materials are a contract and letters concerning a New York City police memorial created by Attilio Piccirilli; two letters to Attilio from Charles Gillette; one letter to Attilio from Paolino Gerli (in Italian); letters from Horatio Piccirilli's son, Nathan, written while he was serving in the Navy during World War II; and newspaper obituaries for Horatio. The earliest items in the collection are photographs of Giuseppe Piccirilli and Attilio Piccirilli.
