American composer and pianist (1898–1937) who was one of the first musicians to attain resounding international success in both the popular and “serious” spheres. While he occupies a secure place among the most gifted songwriters in the history of music, his output extended far beyond the Broadway stage to include concerti and other large-scale concert works, chamber and instrumental music, and the landmark opera Porgy and Bess. Bold vintage ink signature, “George Gershwin,” on an ivory 5 x 2.5 card (affixed to a slightly larger card) bearing two bars of Rhapsody in Blue in another hand. Faint paperclip impression at left edge, otherwise fine condition. Auction LOA John Reznikoff/PSA/DNA and R&R COA.
