As we road trip from Granada to Madrid we’ve noticed the silhouettes of several big, black bulls along the roadside. I did a little research and discovered they were originally billboards created in 1956 for a brand of sherry, Veterano, by The Osborne Group. These bulls were designed by artist Manolo Prieto and have since been ruled by the courts as a symbol of Spain. They now exist on the roadsides but no longer have (or need) the brand name on them.
There are 90 bulls throughout the country. Check out the map and history here!
