These 14 metre high silhouetted images of a bull are a common sight in Spain. They were originally conceived in the 1950s as adverts for the Osborne sherry company and were placed in prominent roadside locations with the brand name "Veterano" written in red across them. In 1994 the EU banned roadside advertising of alcohol however the bulls had become so popular that instead of removing them completely the red logo was painted over in black. There's about 90 of the signs left.
