This 1957 Peruvian airmail issue commemorates the 100th anniversary of the birth of Dr. Daniel Alcides Carrión (1857–1957), the national medical martyr who sacrificed his life studying Oroya Fever. The central portrait depicts Blessed Fray Martín de Porres Velásquez (1579–1639), the famed Peruvian healer and patron of social justice and pharmaceutical workers. Surrounding symbols highlight medicine, healing, and national heritage, including the caduceus, Peruvian flag, and architectural motifs. Printed by Bundesdruckerei, Berlin, it is a richly detailed thematic piece combining religion, medicine, and national commemoration, making it highly desirable for Latin America and medical-thematic collections.
