1961 Spanish Christmas (Navidad) Postage Stamp

This is a 1961 postage stamp from Spain (España) featuring a Nativity scene. The stamp is printed in a deep violet or plum monotone ink on off-white paper. The illustration depicts Mary and Joseph leaning over the infant Jesus in a manger, rendered in a classical, etched style. Key markings include the denomination '1 PTA' (Peseta) in the upper left, 'NAVIDAD 1961' in the upper right, 'ESPAÑA' and 'CORREOS' at the bottom, and the microscopic printer's mark 'F.N.M.T.' (Fábrica Nacional de Moneda y Timbre) below the bottom border. Physically, the stamp features standard comb perforations on all four sides. The condition appears to be used or previously mounted; there is visible wear to the perforations, especially on the left edge where several teeth appear short or blunted. There is significant spotting and light discoloration (toning) visible on the lower white border and within the 'ESPAÑA' text block. No postmark (cancel) is clearly visible on the face, suggesting it might be an unused stamp with hinge remnants or general storage aging. The craftsmanship reflects the high-quality lithographic or photogravure techniques common in mid-century European philately.
