1978 Spain 12 Peseta Europa Stamp - Lonja de Sevilla

This is a 1978 postage stamp from Spain (España), part of the annual Europa CEPT issue. This specific stamp has a face value of 12 Pesetas (12 PTA) and features an architectural rendering of the Lonja de Sevilla (General Archive of the Indies). The stamp is printed using a multicolor photogravure process, primarily in shades of reddish-brown for the building and a light olive-green for the background and text accents. The paper is a typical off-white philatelic grade with standard perforation edges. Notable markings include 'EUROPA' at the top, the CEPT logo in the upper right, 'CORREOS ESPAÑA' at the bottom, and the subtext 'LONJA DE SEVILLA' and 'F.N.M.T. 1978' at the very bottom edge. The stamp appears to be in unused, mint condition with clean perforations and no visible hinging marks or surface scuffs, although a certain degree of yellowing due to age is consistent with its 1970s origin. The craftsmanship reflects the high standards of the Fabrica Nacional de Moneda y Timbre (FNMT), exhibiting sharp detail in the architectural lines and clear typography.
