The essay specifically explores the communication role of graffiti. The main question is: what is one writer telling others with his graffiti? The research was conducted in the city of Pula, in the period from March to April 2015, by observing and interviewing two of Pula`s writers. Research results show that a writer, through his graffiti, primarly sends a message of his existence, and also a message about his way and style of writing. The way and style of writing are exactly the things that will create the reputation of a writer, since they are indicators of experience and quality of work and consequently of hierarchical position within the subculture. By recognising the value of someone else`s graffiti, the writer who observes will understand in which way he should treat it. Factors which contribute to a higher hierarchical position are recognition, frequency of leaving marks in urban areas and location selection. The last factor, location, is very important since it shows to whom the writer is speaking (local or outside writers), but it also shows the writer`s innovation or risk exposure, which will contribute to the graffiti`s value and respect from other writers.
