[1] His career then experienced a turning point when he met the art dealer Emilio Mazzoli, for whom he organised a solo exhibition in Modena in 1983.
[3] The results of this research led Vaccari to expand his exhibition activities beyond the Italian borders and win the admiration of important European institutions.
In the following ten years, his works were exhibited in private galleries,[4] such as the Susan Wyss in Zurich, the Jule Kewenig in Frechen-Bachem (Cologne) and the Thomas Levy in Hamburg[5] as well as in museums such as the one in Horsens, Denmark,[6] the art gallery in Rotterdam, Netherlands,[7] and the Kunstverein in Munich.
[12] In 2008 he took part in the Peking Biennale, while in 2011 he was among the artists exhibited in the Italian pavilion organised by Vittorio Sgarbi.
[15] Later in 2012, Vaccari's reflection on art was linked to an intense epistemological study that led the artist to a new fine-tuning of his own visual language and style.
