1920, 10c. "Flier in Plane Watching Biplane", cleanly cancelled by "CCNA/Cartagena" oval handstamp in violet on picture side of postcard from Cartagena to Barranquilla, dated 22 February, First Flight. Obverse showing 5c. National Post franking, thus being overpaid by 3 1/2 centavos, tied by "Correo Aéreo./Cartagena-Colombia", with Barranquilla receipt c.d.s. in centre. This is the scarcest vignette recorded on cover as only 14 items are known, of which seven are from this flight, with this item possessing the added significance of being a postcard, which was a postal artifact quite infrequently used with vignettes. Scott C5. Ex Augusto Peinado.
