1889 (Aug) Sailor’s concessionary rate envelope from H.M.S. “Griffon” while at Pemba Island (Zanzibar), from the Sullivan correspondence sent to Birmingham, England (received 21 September), bearing Great Britain 1887 2d “Jubilee” tied by partial oval of 7 bars. The envelope was initialled by the Commanding Officer. Very rare as this is the only example from the slave patrol postal history emanating from Pemba, ex Sturton Notes: Michael Sullivan’s duties were as a skilled shipwright. The “Griffon” was on slave patrol duty off the east African coast.
