Excessively rare war-date letter of state, 3pp., folio, Tokyo, 1939, a letter to Peruvian President Oscar Benavides accepting Peruvian Minister Dr. Ricardo Rivera Schreiber to his ambassadorial post in Japan. On Jan. 27, 1941, Schreiber would tell the U.S. Embassy that his spies knew about a planned attack on Pearl Harbor. The gold-trimmed document, in Japanese kanji, is signed by both HIROHITOand KAZUSHIGE UGAKI in Japanese. Ugaki was a Japanese general and Governor-General of Korea, then serving as Foreign Minister. With an original 2-page typed letter on official Imperial Japanese paper translating the document. Document is moderately toned, with beautiful trim and calligraphy, purple ribbon and seal intact, evidence of mounting on verso borders, very good. Signature is superb.
