VERY FINE. THE ONLY RECORDED EXAMPLE OF THE MORTON'S POST STAMP, A SHORT-LIVED PHILADELPHIA POST OF WHICH VERY LITTLE IS KNOWN.
According to Steven M. Roth (Penny Post, Oct. 1993), there is no one named Morton in the city directories who could be positively identified with this post. This cover with the adhesive and a stampless cover (Golden sale, lot 1386) are the only examples of Morton's Post recorded by Roth. Only this cover is dated.
Accompanying the cover is a letter from S. W. Woodhouse Jr. to John J. Klemann, dated Apr. 29, 1930, which states that Woodhouse was the discoverer of the Morton's cover and several other Philadelphia locals among the papers of William Meredith. There is also a note from George Sloane to Frank Hollowbush, which states "Personally I think your cover is alright with the adhesive put on with a wafer."

VERY FINE APPEARANCE. ONE OF A HALF-DOZEN TIED USAGES OF THE NEW YORK CITY EXPRESS POST GREEN STAMP -- THE SO-CALLED "BOYD'S IMPOSTER", BUT OF FAR GREATER RARITY.
Little is known of this post, which issued stamps in Black on Green and Orange on White, found on covers dated from June to September 1847. All of the fifteen or so covers we have seen with 111L1 or 111L2 are addressed to locations outside New York City.
