Railway Post Office (RPO) Cancels, cancels on card or covers, several thousand, running from the late 1870's up until the general end of the RPO system in the 1960's, don't know if there are any great rarities here, but a quick glance reveals quite a few small town to small town usages, some emphasis on the southeast, but generally a good cross-section of the nation's railroad routes. Some mixed condition, but mostly fine to very fine. Estimate $250 - 350.
Realized: $500
