Signal has started a new OOH campaign with a clear focus on improving students’ teeth health, encouraging them to brush their teeth every morning to keep them strong and healthy – therefore they will “add a new student to the strengthening classes”. A wide range of large format billboards can be seen around the city with simple designs and straightforward ad copy. The brand’s logo and the inspiring slogan “A smile that lights up their future” complete the ads. Though small, they have also included their Facebook handle at the bottom and mentioned that this initiative is provided in cooperation with the Ministry of Education.
