During the second half of the 1930s Pieraccini's participation in exhibitions became less frequent, partly because there were fewer appropriate opportunities. She did, however, take part in the 1935 Rome Quadriennale, contributing two monotypes and three paintings ("Ballerina", "Giovannella", "Danzatrice in riposo"). In February 1938 she hosted a personal exhibition at the Galleria Gianferrari in Milan, showing fifty of her paintings, a number of monotypes and many drawings. There were three more relatively low-key exhibitions in Rome itself. In 1941, with Italy at war, Pieraccini teamed up with the sculptor Timo Borlotti for a joint exhibition at the Galleria di Roma. After 1945 there was an exhibition at the "Galleria La Finestra" in 1950 and in the exhibition rooms of the Libreria Macchia in 1956. By this time, however, with the rapid post-war advance in western European art of abstractionism, Leonetta Cecchi Pieraccini could no longer identify herself as a part of the modern art establishment in Rome. Increasingly she had turned, instead, to writing.
