Patterson & Sullivan becomes Patterson & Hall. The studio's key artist in 1939 was William Haines Hall, who had joined the firm in 1925. Alton Painter and Haines Hall were members of the Thirteen Watercolorists (founded by Maynard Dixon and Maurice Logan). Hall was also a member of the Bohemian  Club, producing posters and portraits for various events. When fellow Patterson & Sullivan employee John Atherton won a $500 first place in the 1929 Bohemian Club art show, Atherton moved to New York and invited Hall to visit. While in New York, Hall met many of the illustrators of the day, including Norman Rockwell and Robert Fawcett, whose sister he would later marry. When Sullivan left P&S in 1939, Haines Hall replaced him as partner in the firm. This led to a change in the art agency's name from Patterson & Sullivan to Patterson & Hall in 1939. It was subsequently  changed once more in 1999 from Patterson & Hall to P&H Creative Group which is still in business.
