For the fiftieth anniversary of the massacre in Piazza della Loggia in Brescia (1974), Galimberti takes on one of the darkest pages of Italian history, making a large installation in which period reportage, posters, identity cards and children's drawings become art, both marking and amplifying the tension of a deeply dramatic event, and offering the viewer new ground for thought.

For more than thirty years he has worked almost exclusively with the Polaroid, with which he has developed a highly personal technique of taking an image apart and putting it back together.
