This is a cool postcard I got through a trade with Fabienne from Spain.
It shows the Osborne bull, which is a 14 meters high black silhouetted image of a bull in semi-profile, and is regarded as the unofficial national symbol of Spain. The bull was created in 1956 by Manolo Prieto.
The Osborne sherry company (founded by Thomas Osborne Mann in 1772) erected large images of bulls starting in 1956 to advertise their Brandy de Jerez.
Nowadays the conservation of the bulls is handled by the family of Félix Tejada.
