Bolivian Cents Airmail Stamp with Airplane and Archway Scene

This item is a vintage Bolivian airmail postage stamp, designed with an oblong rectangular shape and a perforated edge typical of postal issues. The primary color visible is a reddish-pink or salmon hue, indicating it might be a 20 centavos (CTS) denomination. The stamp's design is vertically split into two main sections. The upper section prominently features a single-engine propeller airplane in flight, depicted mid-air with some vapor trails suggesting motion. Below the airplane, the country name 'BOLIVIA' is clearly inscribed in a bold, sans-serif font. The term 'CORREO' is vertically aligned on the left side of this upper section, while 'AEREO' is vertically aligned on the right, indicating its airmail purpose. The lower, larger section of the stamp displays an architectural scene, likely an interior view, characterized by a series of arched passageways and a central fountain or statue. The perspective suggests a courtyard or cloister setting. In the bottom left corner of this lower section, the numeral '20' is visible, and 'CTS' (cents) is in the bottom right, denoting the stamp's value. The overall condition appears good, with clean perforations and no immediate visible tears, creases, or heavy cancellations. The printing quality seems consistent with governmental postal issues of the mid-20th century. The stamp appears to be unmounted or lightly mounted, given the absence of hinge remnants or heavy cancellation marks over the central design. The color saturation is fairly uniform, and the design elements are sharply defined.
