Get 5 U.S. Stamps Once Overprinted for Use in the Panama Canal Zone
On June 24, 1904, postal service was established as part of the US Department of Revenue under the supervision of the Treasurer of the Canal Zone, Paymaster E.C. Tobey. On this day, post offices were opened in Ancon, Cristóbal, Gatun, Culebra, and Balboa. Railroad station agents operated as postmasters.
Overprinted Panama stamps were in use for less than a month. On July 18, 1904, they were replaced by US postage stamps overprinted "Canal Zone." This is your chance to get five of those stamps (without the overprints) in one easy order.
