US Carrier Studies
By: Donald B. Johnstone - 2003
This exhibit begins with the official carriers, the Franklin and Eagle carrier stamps, showing their proofs, reprints, and usage by city alphabetically. This is followed by evidence of carrier service activity in cities arranged alphabetically, with use of semiofficial carrier stamps, regular postal issues to prepay carrier services, as well as the numerous and varied carrier markings employed. The major carrier cities, New York, Philadelphia, Boston, and Baltimore experienced more carrier activity than other carrier cities, and therefore provide more examples of this activity than do the other cities included here. Other cities with carrier service during tile carrier fee period shown here include Brooklyn, "Charleston, Charlestown, Cincinnati, Cleveland, Louisville, Lowell, New Orleans, Portland, and Washington.

Such companies are called the Independent Mails. And analysis of its postal history reveals that Overton's was able to maintain business operations despite intense competition from other private companies. It survived by acquiring the agents and offices of other companies, offering "cheap postage rates" between cities, and providing early local address delivery which the other independent mail companies did not do.
