(April 25, 1878 to August 10, 1887)
South Charlotte, Maine, January 11, no year date, on letter to Laurence, Massachusetts. The stamp appears to be a Continental Banknote Company printing on hard paper (first issued in 1873) which implies that the cover could be from the June 7, 1875 to March 29, 1878 office or the April 25, 1878 to August 10, 1887. The American Banknote Company issued stamps of this design on soft paper beginning in 1879, which could only be used by the April 25, 1878 to August 10, 1887 office.
