Description: This beautifully engraved definitive postage stamp from Switzerland (Helvetia) showcases the nation's mid-century marvel of civil engineering, the Grimsel Dam and Reservoir located in the Bernese Alps. Rendered in a rich brown-carmine ink, the architectural vignette frames the sweeping, curved concrete retaining wall of the reservoir juxtaposed against stark, deeply etched mountain cliffs. In the distance, a majestic jagged range of snow-capped alpine peaks punctuates the upper skyline. The bold designation 20 Centimes is integrated smoothly into the lower-left edge, flowing seamlessly into the classical name of the Swiss Confederation, "HELVETIA", which anchors the baseline in clean, capitalized typography. A partial black ink circular date cancel cuts across the left margin, highlighting its regular operational use in the Swiss federal postal network.
