The poster shows an idea of EX_TREMISM (making extremism history) as an exclusion of harmfull and violent activities. The composition of abstract elements unveils in fact two characters "E", "X". The "E" in front means elimination, exclusion, prevention and the "X" in back means an extreme factor eliminated and banned. The concept behind the poster is to show in a very simple and plain way the contrast between oppostie attitudes and their roles in the present world.
