The Reilly and Britton Company, known after 1918 as Reilly & Lee, was an American publishing company of the early and middle 20th century, best known for children's and popular culture books from authors like L. Frank Baum and Edgar A. Guest. Founded in 1904 by two former employees of George M. Hill's publishing company, Frank Kennicott Reilly and Charles Britton, the company would later be guided by William F. Lee until it was acquired by the Henry Regnery Company in 1959.
