AEGEAN ISLANDS: Chios 1867: "SAKIZ" intaglio seal tying a 1 piastra 1867 (second issue) on entire folded letter in Greek, with dateline Scio 18/30 December 1867, sent to "Poste Vice-Reali Egiziane CONSTANTINOPOLI 3.Gen.7" blue (probably the postman didn't change the digit for the year). According to Peter Smith (p. 569) this Post Office officially opened in July 1870, but the Post Office was already in operation before then. Two more covers are known from earlier dates. Sorani signature next to the stamp
