The volume accompanies the first great anthological exhibition dedicated to Agostino Bonalumi (1935-2013) in the city of Milan, a few years after his death. From the beginnings with Enrico Castellani and Piero Manzoni, through the sixties in contact with major European groups until the recent international rediscovery, the volume documents the multi-faceted and at the same time rigorous activity of one of the greatest interpreters of abstractionism in the world, who managed to overcome the two-dimensionality of painting through works on canvas that are transformed into sculpture, thanks to the technique of 'extroflexion'. The volume, with texts by Marco Meneguzzo and Philip Rylands, is complete with an anthology of writings about the artist and bio-bibliographical sections.
