Original concert program, signed and inscribed by Menuhin on the second page of the program listing "Aux chers collègues M. et Mme Grumiaux" and signed also by his wife Diana "Avec sympathie et compréhension collégiales." Bruxelles, Palais des Beaux-Arts, 20/11/1954. 4to. Cover with a Piaz portrait of Menuhin. Some light marks and wrinkles to covers, else fine. A remarkable association between the two great violinists.
