Burbank (1849–1926) was a pioneer in agricultural science, credited with developing over 800 new plant varieties during his career. His contributions included innovative fruits, vegetables, and ornamentals, notably the spineless cactus and the plumcot. Most famously, he cultivated the Russet Burbank potato, which remains the most widely grown potato in the United States—and is the primary variety used for McDonald’s French fries.Accompanied by a Certificate of Authenticity from John Reznikoff, one of the world’s premier autograph authenticators for PSA, JSA, and numerous auction houses.Dimensions: 6″ x 8.25″Medium: Signed Photograph (bookplate portrait)Signature: Luther Burbank, dated January 23, 1909, Santa Rosa, CA
