This material belongs to a program for the Tri-City Symphony Orchestra — Albany, Troy, Schenectady — in which Warner was soloist in the Schumann Piano Concerto. The program, from the period 1940-1941, is undated.

Among the most treasured possessions of Major John Warner, Superintendent of New York State Police, and fine concert pianist, is a portrait of Charles Marie [Charles-Marie] Widor [1844-1937] . . . On it is inscribed in the aged master's own hand: "A mon frère" [actually "a son confrère Jean Warner Ch M Widor Dec. 1910"]. . . . During that memorable period of study under Widor, Major Warner also studied piano under Harold Bauer and later had a few lessons in Chopin with the master interpreter of that composer's work, Vladimir De Pachmann.
