1855 cover to Port Carbon, Pennsylvania, endorsed "Per Holden Stage", 1851 3c Dull red (11) tied by black "Steam" handstamp, red "New Orleans La Apr 8" datestamp, very fine, a remarkable cover carried by three different modes of transportation

This cover is an example of the symbiotic relationship among stage, steamboat and railroad lines (in this case in Louisiana). This cover would have been carried on the Opelousas and Great Western Railroad to Bayou Lafourche. At Bayou Lafourche, it would have been put on the stage coach and carried to Thibodaux, where it then was placed on a steamboat heading to New Orleans.
