From white flags for peace to the black flag of pirates, and the rainbow flag for pride, in the folds of the flag there is an almost magical power. From the legendary and conquering flags of history books to the Stars and Stripes planted on the moon, they move with the command of icons and trophies. One of the oldest forms of media in the world, the flag now occupies a renewed place in public space. This is increasingly true in virtual public and online social networks. As a new media, it invites us to raise our heads to the sky. The flags of artists have become vectors of communication.
