In 1956, the trademark was created that made Osborne famous around the world - not least because of the ongoing presence of the almost 14-meter-high silhouettes on Spain's highways. The Osborne bull was originally planned as a large billboard on Spanish roads, where it was to serve as an advertisement for the Veterano brandy. In 1956, the Spanish agency Azor was commissioned to design an advertising board for the Veterano brandy. The designer Manolo Prieto, who worked there, was tasked with implementing the design and developed the Osborne bull, which is now known around the world. Over time, it developed from a trademark into a national symbol of Spain. The Osborne bulls that can be seen today no longer have any advertising lettering. There are currently around 90 bulls distributed unevenly across Spain, 21 of which are in Andalusia.
