1987 Spain Europa Cept Stamp - Office Building (Edificio Windsor)

This is a vertical rectangular postage stamp issued by Spain in 1987 as part of the annual 'Europa CEPT' series. Centrally featured is a modern architectural illustration of an office skyscraper, identified by the lower text as the 'Edificio de Oficinas F.J. Saenz de Oiza Madrid,' famously known as the Windsor Tower. The artwork utilizes a lithographic printing process with a palette of terracotta red for the building facade, set against a pale blue sky and green foliage at the base. In the upper left corner, the CEPT (Conference of European Postal and Telecommunications Administrations) logo is present. The denomination '19 correos' appears in the bottom left, with 'españa europa' in stylized brown typography in the bottom right. The stamp features standard comb perforations on all four sides. Notations at the very bottom indicate the year '1987' and the printer 'F.N.M.T.' (Fábrica Nacional de Moneda y Timbre). The condition appears to be 'Mint Never Hinged' (MNH), as the perforations are intact, the colors are bright without fading, and there is no visible cancellation mark or hinge residue visible from the front. The paper is clean with no signs of foxing, creases, or tears.
