Original studio photograph signed by Herbert Hoover, 31st President of the United States. PSA has encapsulated the photo, certifying the signature as "Authentic" and the photo as Type I Authentic. Hoover has beautifully inscribed the photo "Kind Regards of Herbert Hoover" in blue fountain pen (grading 8/10) along the bottom white border. The photographer's embossed credit stamp, "Harris & Ewing, Washington D.C.," appears in the lower left corner. The photo (7.5x10.75") displays light chipping along the top border from having once been matted and framed.
