[2] In 1933 he takes part with five paintings to the exhibition Cinque giovani pittori veneti (Five young painters from Veneto) in the Gallery Il Milione in Milan.
He joins Italian avant-garde movements and participates, with Emilio Vedova and others, to the creation of the Fronte Nuovo delle Arti.
Peggy Guggenheim, who visited that exhibition, bought there the painting Primo maggio (in English: May Day) of Pizzinato and later donated it to the MoMA, where it still is.
In 1949 works of Pizzinato were included by Alfred Barr and James Thrall Soby in the exhibition 20th Century Italian Art at the MoMA.
The painting Un fantasma percorre l'Europa, which is considered as one of Pizzinato's masterpieces, is dated 1950 (exhibited in the Galleria d'Arte Moderna Ca' Pesaro, Venice).
From 1950 on he deliberately brought the themes of his paintings in line with his political beliefs (e.g. works entitled Terra non Guerra, I difensori delle fabbricche, Saldatori).
