1941 10c Canal Zone Official Airmail, Gaillard Cut, Orange, Panama Canal Overprint Type I

Scott #CZCO2 is a 10-cent orange Canal Zone Official Airmail stamp issued in 1941, created by overprinting the standard Gaillard Cut airmail stamp with "OFFICIAL / PANAMA CANAL" in black — this example bearing the Type I overprint.

The stamp was produced for use by federal government offices located within the Canal Zone, which required their own designated official mail stamps distinct from those available to the general public.

The Gaillard Cut depicted on the stamp is one of the most celebrated engineering achievements in American history. Originally called Culebra Cut — Spanish for "Snake Cut" — it is the nine-mile channel blasted and dug through the Continental Divide to complete the Panama Canal. The work was led by U.S. Army Colonel David du Bose Gaillard, who drove his crews through treacherous terrain plagued by landslides, tropical disease, and unstable geology. Gaillard died of a brain tumor in 1913, just before the canal was completed, and the cut was officially renamed in his honor in 1915. The dramatic image on the stamp — a biplane soaring above a ship passing through the steep walls of the cut — perfectly captures the audacity of both achievements.

Because Canal Zone Official stamps were produced in far smaller quantities than standard issues and used only within the administrative machinery of the Canal Zone government, they see far less frequently than their regular counterparts. The Type I overprint designation adds another layer of interest for specialists who pursue the varieties within this series.
