A very important work was commissioned to Cassinari in order to be placed in Santa Barbara church in Metanopoli: it is the so-called La Madonna della Speranza, which was completed in 1966. Some personal exhibitions were mounted in the Gissi Gallery in Turin, in the Zanini Gallery in Rome, in the Macchi Gallery in Pisa and even in the Rubio Gallery in Buenos Aires. He also exhibited three of his works at the exhibition entitled Mostra dei grandi Premi, which was held in Ca’ Pesaro during the XXXI Biennial of Venice; moreover he took part with five paintings in an exhibition about Italian painting in the post-war period (Il dopoguerra-la pittura italiana dal ’45 al ‘55), which was mounted at the Castello Estense in Ferrara. Together with Birolli, Dobezanski and Morlotti, Cassinari exhibited some of his works at the North-South Gallery of Lugano, with Campigli and Soldati at the Bergamini Gallery of Milan, and with Birolli, Guttuso and Morlotti at the Annunciata Gallery of Milan too.For the publishing house Cappelli of Bologna he illustrated Horatio’s Odes and for the publishing house Scheiwiller De Marchi’s El noster Dom. In the same year he opened his studio of Gropparello again.The works of this period show a new personal and poetic realism: sunflowers, cocks, flowers,pomegranates and storms will be the favourite subjects for his next creations.
