Florence became the first first lady since Frances Cleveland whose face was so recognizable to the public, as she frequently appeared in newsreel footage alongside Warren unveiling statues, attending baseball games, and dedicating the Lincoln Memorial. Several flowers were named in her honor, and the composer David S. Ireland wrote a song called "Flo from Ohio." Due to the popular interest in psychoanalysis, some psychological profiles were written of her in newspapers. The First Couple increased their popularity by attending movie screenings and meeting actors, who were previously seen as vulgar by high society. Al Jolson was a frequent guest, and Florence gave D.W. Griffith a tour and lunch at the White House. Florence became the first first lady to appear in movies with her signature wave to crowds. Evalyn McLean taught her how to operate a camera and she made some films of women at the Potomac Park Civic Club.
