This is the first Complete Catalogue Raisonne of all the limited-run artistic editions realized by Francesco Conz, a mysterious impresario who squandered his millionaire fortune to promote the artists of his time. "Having been very rich, I had no pleasure in collecting 'rich stuff', already packed. I was looking for a more refined answer to my approach to art and the creative process behind it". Nicola Viviani graduated in Classical Stuides, Cultural Heritage and got a master degree in Art History. Since the Nineties he was deeply influenced by Francesco Conz, who consider to be his mentor, and furthered his studies about the contemporary vanguard's artistic groups such as Viennese Actionism, Fluxus, Lettrisme, Visual and Concrete Poetry, Gorgona, Zaj, Mail Art and Beat Generation.
