Two posters
In these two posters of the exhibition Simmetria, giochi di specchi - Symmetry, playing with mirrors there's a good representation of the main point of the exhibition: a casual sequence of images that recall symmetry in various ways (on the left) are put in order (on the right) according to their geometry in the room of mirrors (or, more precisely, according to their group of symmetry).
