From 1967 onwards Guy Vandenbranden started to spray cellulose lacquer directly on panels with the aim to create visual illusions (akin to the Op Art).
[3] In 1959, Vandenbranden and Jef Verheyen planned to open an Antwerp avant-garde gallery to bring together artists with a like-minded spirit.
Piero Manzoni, Jean Tinguely and Lucio Fontana had pledged to work together, but in the end this project jumped and G58 took the role as platform for a new (European) avant-garde at the Hessenhuis in Antwerp.
[4] After their project ended, Vandenbranden and Jef Verheyen forged plans with Englebert Van Anderlecht to the establishment of the New Flemish School in 1960.
This artists' group, including Paul Van Hoeydonck, Jan Dries and Vic Gentils, aimed to promote their art internationally with exhibitions in Germany, Switzerland and Italy.
