Three items: 1937 TLS in Greek, signed “D[imitri] Mitropoulos”; 1939 TLS sending thanks, signed “D. Mitropoulos”; and a 1933 TLS on a youth concert, signed “Leopold Stokowski.” In very good to fine condition overall, with folds touching signatures, marginal tape remnants to Stokowski, and scattered soiling and handling wear with a few tiny tears. R&R COA.
