These Uruguay commemorative stamps honor Dámaso Antonio Larrañaga (1771–1848), a prominent priest, naturalist, and one of Uruguay’s early intellectual figures. The stamps feature a detailed side-profile portrait, accompanied by symbolic botanical elements and scholarly imagery reflecting his contributions to science and education. Issued in two denominations—20 centésimos (turquoise) and 40 centésimos (brown)—the pair represents a classic mid-20th-century Uruguayan definitive design style. Their clean typography and elegant engraved portrait make them attractive additions for collectors specializing in Latin American historical personalities or scientific heritage themes.
