KESAN- Prevention Centre of Heraklion Crete co-organised the 12th Panhellenic Conference meeting for addiction prevention related entities, with the support of the Panhellenic Network for Addiction Prevention Entities and assigned us to design the poster as well as the entire communication material of the event. The basic elements of the composition are, the Heraklion castle, which emphasises on the hosting place of the event, as well as some concept symbols, the sea and the sun; the latter can also be viewed as a target and symbolises the conference itself, with the speaker in the centre and all the participants around him or her.
