Posters are highly efficient communicational tools since they are accessible to wide masses of people-they are part of the street semiotic. As posters are supposed to cause a great impact considering that neither passersby nor drivers will stop to read them, they should be precise regarding the message and the elements used to convey it. In this way, an intelligible and closely analyzed poster will work as a key marketing element that is capable of conveying an unforgettable message immediately.
