1920 censored post card to the U.S.A. with a 10m and 3m (damaged at the upper left) cancelled PORT SUDAN 7 JA 20, that has a violet boxed âKâ and a triangular PASSED CENSOR 39 SUDAN h/s. This censor mark is very scarce, Collier recording only 2 known and later than his last listing of June 1919. A scarce card to an unusual destination.
