This 5 pesetas postage stamp from Spain, issued in 1966, features the heraldic emblem of Zaragoza, the historic capital of Aragon. The design presents a crowned golden lion rampant on a red shield, symbolizing strength and valor, with the city's name inscribed above. Part of Spain’s long-running Provincial Arms definitive series, this issue reflects the country’s deep regional pride and heraldic tradition. Printed by F.N.M.T. (Fábrica Nacional de Moneda y Timbre), it remains a classic among collectors of Spanish heraldry.
