Issued in November 1969, this Argentine commemorative stamp celebrates Lions Clubs International, a global service organization devoted to humanitarian causes. The minimalist design by H. Viola features a bold black “L” on a green background with the red and gold Lions emblem prominently displayed. Printed by Casa de Moneda, the stamp reflects Argentina’s appreciation of civic and charitable organizations active within the country. It carries a face value of 20 Pesos and stands out for its clean modernist aesthetic and symbolic simplicity.
