A FINE AND EXTREMELY RARE COMBINATION. ONLY THREE COVERS WITH THE PHILADELPHIA 7LB3 CARRIER STAMP AND 5-CENT 1847 ISSUE ARE RECORDED.
Census information is reported by Larry Lyons in The Penny Post (July 2006). Ex Gibson and Boker. With 1993 Jakubek certificate
A VERY FINE AND ATTRACTIVE COVER WITH THE "LS" PHILADELPHIA CARRIER STAMP.
This May 12 postmark on a clearly-dated 1849 letter is an appropriate date of use of the "LS" stamp. The Philadelphia carrier service was reorganized in February 1849, and stamps were issued at that time. Lyons reports 12-15 covers with 7LB4.
VERY FINE. APPROXIMATELY TWELVE TO FIFTEEN EXAMPLES OF THE BLACK LITHOGRAPHED CARRIER STAMP ARE REPORTED, AND ONLY THREE ARE KNOWN IN COMBINATION WITH THE 1851 ISSUE. THIS TIED USAGE IS EXTRAORDINARY.
Ex Piller. With 1984 P.F. certificate
AN EXTREMELY FINE EXAMPLE OF THIS EXCEEDINGLY RARE CARRIER STAMP. NO MORE THAN A DOZEN EXAMPLES OF 7LB14 ARE KNOWN TO US.
The Type C31 stamps were ordinarily left uncancelled; this probably was removed from a cover. The pencil lines at bottom and right are characteristic layout lines.
Ex Caspary and Middendorf. With 1991 P.F. certificate stating that the stamp is genuine. Scott Retail as an off-cover stamp
VERY FINE ON-COVER EXAMPLE OF THE PHILADELPHIA U.S.P.O. DESPATCH CARRIER STAMP ON THE SHEET MARGIN OF THE ONE-CENT 1851 ISSUE.
The Philadelphia carrier stamps printed on the sheet selvage of imperforate 1c 1851 stamps hold a unique position in United States philately. Elsewhere in the world there are very few instances in which sheet selvage was used to produce adhesive stamps -- the Emory Va. Confederate provisional and early stamps of Zanzibar come to mind as other examples. Two handstamps were used to create the Philadelphia carrier stamps: the Eagle oval (Scott type C31), which produced 7LB16, and the large oval (type C32), from which 7LB18 was made. These were probably necessary after supplies of the Eagle Carrier ran out in 1856.
