Chaumont Poster Festival 2009 Workshop. Being Twenty · Chaumont holds an annual International Poster Festival involving professional designers and students. The festival is split into a competition and workshops. In 2009 it was their 20th Anniversary. · Being twenty is a major moment for everyone. Transition from childhood and adolescence to adulthood, from emotional and material dependence towards an existential autonomy in perpetual progress. Daily things take up an important space that one could not have imagined and they are mixed up with more complex ideas on life one has created while maturing their own thoughts and critical sense. ·
