The European Commission's Open Day in Brussels on 4 May was an occasion to focus on the European Year of Citizens 2013, and one of the day's many activities proved to be one of its highlights too: the world's largest citizens' postcard began the day as a blank slate, but by the end of the day over 3,000 citizens' photographs adorned its 35 m2 surface area.
A team of hosts and hostesses dressed in the vivid orange visuals of the European Year of Citizens, went about inviting visitors to the Commission's headquarters at the Berlaymont building in Brussels to have their portrait photo taken for the giant postcard.
The Vice-President of the European Commission, Viviane Reding, was among the thousands of citizens who volunteered to have their photograph taken on the day.
"EU is for you, it is for us, and we construct it all together" wrote Vice-President of the European Commission, Viviane Reding on the back of her postcard.
On the back side of each photo, these camera-friendly people could write down a message to the European Commission. In this way, the giant "citizens' postcard" message gave a tangible example of the motto of the European Year of Citizens: that "it's about Europe, it's about you!"
