Foundy and Ord. Works, Selma, Ala.", both strips have large margins to
just touching design in places, rich color, strip on face creased between
two stamps and in right pair, couple toned spotsVERY FINE. A REMARKABLE USE OF THE 2-CENT GREEN ON A COVER TO FAMED CONFEDERATE NAVAL OFFICER CATESBY JONES. THIS IS THE LARGEST RECORDED FRANKING WITH THE 2-CENT LITHOGRAPH.
The absence of a cancellation on the second strip on back indicates that the Mobile post office either weighed the letter and determined that it was under the half-ounce limit (for the 10c rate) or that the postal clerk never looked for additional stamps on back. The two strips definitely join together to form a complete row from the original sheet.
