Republica de Colombia 20 Centavos Postage Stamp (Waterlow & Sons)

This item is a postage stamp from the Republic of Colombia, denominated in 'VEINTE CENTAVOS' (twenty centavos), as indicated at the bottom. The stamp features a portrait-style illustration of a figure with a distinct cap or headwear, possibly a historical or allegorical representation, set within a circular frame. Surrounding the portrait, the text 'REPÚBLICA DE COLOMBIA' is clearly visible along the top arc. The denomination '20' is displayed in numeric form within decorative ovals at both the lower-left and lower-right corners of the central image. The word 'CORREOS' (postage/mail) is inscribed above the 'VEINTE CENTAVOS' text. The overall color scheme appears to be shades of blue or teal (due to lighting, it's hard to be definitive but it's clearly monochromatic or duotone with a dark main color) against a lighter paper background. The stamp has a classic rectangular shape with perforated edges, typical of postage stamps. The bottom edge of the stamp clearly bears the manufacturer's imprint: 'WATERLOW & SONS LD, LONDRES', indicating it was printed by the renowned British bank note and stamp engravers. The stamp shows evidence of being used, as there is a visible cancellation mark, which appears to be circular, partially obscuring the top right of the portrait and extending into the frame. The condition appears to be fair to good for a used stamp, with the perforations seemingly intact, though there is some unevenness in the paper color around the edges, possibly due to handling or age. This stamp likely dates from the late 19th or early 20th century, given the style and the printer mentioned.
