Original poster from a 1958 performance of the great quartet, signed by all four members: Josef Roisman, Alexander Schneider, Mischa Schneider, and Boris Kroyt. The group performed at Scott Hall, Dallas, Texas, on January 29, 1958. Some water damage and a small loss at the lower left, but signatures unaffected. 12 x 18 inches. Signed photographs of this ensemble are uncommon but this is the only signed poster we’ve ever encountered.
