Topic of this year’s Festival of used books (Poreč City Library): ‘The book reveals what reality hides’, was the inspiration for the poster whose graphics and application symbolize a “dog- ear” on a book, behind which new worlds hide. By placing the poster in the top-right corner, like a “dog-ear” on a huge book, the poster actually takes over the whole advertising surface thus creating one huge festival. Furthermore, the “dog-ear” symbolizes the secondhand nature of books, creating a link with the character of the festival. The festival transmits the importance of using secondhand also in terms of savings (one poster on the whole advertising surface). Already used billboards were used for increasing the desired effect of communication.
