Streetcars on Lexington Avenue, as seen from the northwest corner of 102nd Street, 1931. Nicknamed "crackup hill" or "Duffy's Hill" for the Tammany Hall Alderman Michael James Duffy, who built rowhouses in the area, this block was the site of frequent traffic accidents. Visible in the lower-left portion of the frame is the entrance to the 6 train at 103rd Street.

East Harlem, the neighborhood covering a broad swath of Upper Manhattan north of 96th Street and East of Fifth Avenue, has historically been known for its prominent populations: in the early 20th century, Italian Harlem; the Latino community of Spanish Harlem in later years. These photo's from the New York Public Library's Milstein Division provide a snapshot of daily life uptown, from street scenes to Feast Day parades.
