Three oil paintings, two on the front and back of a panel, and the third on canvas board. All signed at the bottom. They are presented in book-hinged frames, with a view of Milan Cathedral on the outside of the panel, and two views of tenement houses on the inside. Giuseppe Viviani, an artist from Pisa, primarily established himself as an engraver, a craft he taught for a long time at the Academy of Fine Arts in Florence. He also devoted himself to painting, seeking above all to express emotions through color, so much so that he called them the "colors of the soul."
