1940 Coronado Cuarto Centennial 3-Cent US Postage Stamp

This item is a 3-cent United States postage stamp, commemorating the 400th anniversary (Cuarto Centennial) of Francisco Vázquez de Coronado's expedition (1540-1940). The stamp is rectangular with perforated edges, typical of postage stamps, and appears to be housed within a protective mount or sleeve, suggesting it is part of a larger collection or has been preserved. The dominant color of the stamp is a muted purple or violet hue. The central design depicts Coronado, likely on horseback or leading his expedition, surrounded by other figures, some on horseback and others on foot, against a backdrop that suggests a landscape. The figures are rendered in a classical, illustrative style. "U.S. POSTAGE" is printed at the top left, and "THREE CENTS" is at the top right, with the numeral "3" prominently displayed within an oval or shield shape on the left side. The bottom of the stamp clearly reads "1540-CORONADO CUARTO CENTENNIAL 1940". The stamp exhibits a generally good condition, with no immediately visible tears or significant creases, though a definitive assessment of its gum or backside is not possible from the image. The perforations appear intact. The color saturation seems relatively consistent, suggesting it has not suffered from excessive fading. The overall impression is that of a well-preserved philatelic item from the mid-20th century, representing a historical commemorative issue.
