By 1903, Sloan had produced almost sixty oil paintings but had yet to establish a name for himself in the art world. In April 1904, he and Dolly moved to New York City and found quarters in Greenwich Village where he painted some of his best-known works, including "McSorley's Bar", "Sixth Avenue Elevated at Third Street", and "Wake of the Ferry". He became increasingly prolific, but he sold little, and he continued to rely on his earnings as a freelancer for "The Philadelphia Press", for which he continued to draw weekly puzzles until 1910. By 1905, he was supplementing this income by drawing illustrations for books (including Wilkie Collins' "The Moonstone") and for such journals as "Collier's Weekly", "Good Housekeeping", "Harper's Weekly", "The Saturday Evening Post", and "Scribner's". Sloan participated in the landmark 1908 exhibition at the Macbeth Galleries of a group that included four other artists from the Philadelphia Charcoal Club (Henri, Glackens, Luks and Shinn) as well as three artists who worked in a less realistic, more impressionistic style, Maurice Prendergast, Ernest Lawson, and Arthur B. Davies. The group was afterward collectively known as "The Eight." The Macbeth Galleries exhibition was intended as a rebuke to the restrictive exhibition practices of the powerful, conservative National Academy of Design. Sloan organized a touring exhibition of the paintings from that show that traveled to several cities from Newark to Chicago and elicited considerable discussion in the press about less academic approaches to art and new definitions of acceptable subject matter.
