cover 1855 (14 Mar.) entire from Halifax to Boston, U.S.A., bearing 1851-57 1d. red-brown pair with small to large margins and 3d. blue with good to large margins, both clearly tied by oval grids, showing handstruck "5" with, on reverse, despatch and "BOSTON/BR PKT" c.d.s.; one 1d. crossed by light ironed-out filing crease, nevertheless a very fine and pleasing example of the five pence packet rate to U.S.A.
