This hand-colored 1867 lithograph by architect Samuel Sloan (1815–84) was a plate in an architectural design book; it illustrated a perspective view of a symmetrical, Italian-style, suburban mansion. The mansion was located on the edge of Rittenhouse Square in Philadelphia, on the northeast corner of Eighteenth and Locust Streets. It was built in 1855–57 after designs by Samuel Sloan, for Joseph Harrison, Jr., a prominent Philadelphia man known for his innovative design of a locomotive engine. In this view, pedestrian traffic is seen passing in front of the home, including two gentlemen on horseback, a man and woman walking, and a horse-drawn carriage. This print was produced by the firm of Louis N. Rosenthal, a pioneer chromolithographer who operated the Philadelphia firm Rosenthal’s Lithography with his brothers Max, Morris, and Simon circa 1851–72. Rosenthal was born in Turck, Russian Poland around 1824, and immigrated to the United States in 1848.
