Original Description: Hell’s island gets letters from heaven. Marines of the Fourth Division receive airmail in the most literal sense of the word when planes flew over Iwo and parachuted mail bags to the beach. The post office was in operation on the tenth day of the campaign. Setting up the sign post are (left to right), Sergeant B.D. Boyant, of Spartansburg, PA. and Corporal Kenneth E. Hales of Pasco, Washington.
