This striking Colombian airmail stamp, issued in the 1960s, promotes correo expreso—Colombia’s expedited air-delivery service. Featuring a bold red frame and a dynamic aircraft soaring above a stylized envelope, it visually reinforces the theme of rapid dispatch (Entrega Inmediata). Printed by De La Rue de Colombia, the design is crisp and modern, with fine halftone shading and elegant typography. A desirable addition for collectors of Latin American postal history, aviation-themed issues, and mid-20th-century airmail services.
