Issued by Peru in 1967, this airmail stamp commemorates the 50th anniversary of Lions Clubs International (1917–1967). The design prominently features the organization’s classic emblem — two lion profiles facing opposite directions around the bold “L” — set against a clean sky-blue background symbolizing service and vision. The inscription “Cincuentenario” marks the milestone celebrated worldwide that year. With a denomination of S/.1.60, this issue reflects Peru’s participation in a global philatelic tribute to one of the world’s leading service organizations.
