This commemorative 20 Pesos stamp from Argentina was issued in 1968 to mark the 100th anniversary of Galería Witcomb, one of the country’s most historic and influential art galleries. The stamp features a finely rendered monochrome artwork of a seated woman beside a clay vessel—representing Argentina’s strong tradition of cultural exhibition and the gallery’s role in promoting national art. Printed by Casa de Moneda, it is a sought-after issue among collectors of Latin American art-themed philately. Attractive deep-crimson shading enhances the classical composition.
