cover CUBA: 1870? envelope from Amherst to Trinidad de Cuba, marked "Via New York", bearing Large Queen ½c. pair (faults), 3c. and 6c., all very lightly cancelled and with additional ink pen cross and showing, on reverse, poor despatch and arrival c.d.s.; the cover a little soiled and slightly truncated at left, nevertheless a fine example of the very scarce 10c. per half ounce letter rate.
