1870 outer wrapper to Philadelphia with a (1d) lake and a 4d tied by black TRINIDAD AU 9 1870 cancels. A red TRINIDAD PAID AU 9 1870 cancel is alongside. A New York Steamship AUG 21 ‘10’ (the month inverted) cancel also ties the stamps. At the lower left is an O’Connor Brothers forwarding agents h/s. A St. Thomas AU 13 70 transit cancel is on the back. Minor faults to the wrapper but an uncommon item.
