This 1927 piece has the mysterious "R.S." as the artist's credit. Apparently these initials are pretty common in the sheet music world and have been the subject of conjecture. Conventional wisdom settles on Rosenbaum Studios, run by Morris Rosenbaum who employed a group of illustrators. These artists included William Wallace Denslow, Emil James Bistran, Harold Guenther Breul, Mortimer Flaum (hi Morty!), Reinhold William Gundlach, and James Murray Mitchell.
