New York: 1891. unbound. Exceptional and rare calling card, 2.5 x 4 inches, bearing his title "Kammervirtuose" and Royal Pianist with three bars from his classical composition "Spanish Serenade" of which Grunfeld jokingly titles it "Little Serenade," due to a lack of room to write out a more detailed title. Signed in full and dated "New York, Sunday 11/25/1891." Fine.
Grunfeld was an Austrian composer and prodigy pianist. In 1888 he was appointed Court Pianist to Emperor Wilhelm I of Germany. He was a major influence on German-Austrian classical composers for his entire life.
