1799, Sept. 1-0. Ship's register cover from Havana to Campeche (Mexico), registering the "La Concepcion" schooner, struck in red-purple by "Yndias" straight-line and scarce "Havana/Franco" oval (P.E. 15) postmarks. Cover toned as expected. The only document recorded of this nature exhibiting these postmarks used in conjunction. It is to be remarkably noted that these postal documents are of great scarcity in the whole American continent. Ex Kouri.
