Under the title "Disclosure", what is probably in terms of its scope and quality the most outstanding private collection of Günter Brus' work is now presented for the first time. Over the past few decades, the THP Private Foundation has built up an extensive collection of the artist's work. This ranges from one of his first watercolours from the late 1950s through to the latest works during the Corona lockdown of 2020. The comprehensive monography contains major works from all of the artist's creative periods and traces vividly the development of the exceptional artist Günter Brus from Viennese Actionist to celebrated picture-poet.
