Just another picture of Lloyd Buford Threlkel, Honorary Degree Member of the Nose Flute Hall of Fame. It would be nice to find the original picture, since this one looks to be a multiple photocopies result.
And just for the pleasure:
Low Down Blues (Eubie Blake / Noble Sissle), 4-29-1927, St. Louis, Missouri, Okeh 8469.
