cover 1858 (12 May) entire to London, bearing 1855-58 2d. Pl. 6 and 1857 4d., both placed at lower left and clearly cancelled "G", showing two strikes of "GIBRALTAR/SHIP LETTER" d.s. (both crossed by filing crease) and, on reverse, Ship Letter London d.s. in red; the entire with a few minor faults, nevertheless a rare and most attractive franking. Photo
