In the third decade of the 20th century, opened a public street advertising company, with an entrepreneurial spirit that began a new activity for the time. Protto burst into the market with signs painted in the city and on the highway; a new advertising medium that came to compete with the oral and written press. The OOH became a leading industry in terms of advertising, the ad placed in strategic places is always there, to be seen and to show what is intended. Today our firm has kept pace with the market requirements and continues to be a leader due to experience, good techniques and responsibility. Our work systems, state-of-the-art machinery and everything in force in technology applied to advertising is in our company.
