This is an extremely rare single-stamp franking with the 1879 90¢ American Bank Note Company Issue. Power Search located only two other intact covers with this stamp, and this is the only one with a single stamp. The records of The Philatelic Foundation contain two others, both mixed frankings and both seriously defective.
