Paradigm of cosmopolitan design, Metropolis is conceptual aesthetic. It expresses the aspiration to growth and construction. Metaphor of absolute peace. Suspended between cubism and modernism, the vase is made in a limited edition of 500 numbered pieces. This is the creation chosen by Mario Cioni, and C., author of the collections Tondo Doni and Mario Cioni, to celebrate the 50 years since its founding in 1958.
