From 1951 onwards, Guy Vandenbranden left figuration behind and started to work in a lyrically abstract way. In 1952, Vandenbranden ended up in the Brussels art scene and became friends with Pol Bury, Jo Delahaut, Kurt Lewy, Jean Rets and Jean Milo. Thanks to these contacts, Guy Vandenbranden joined the artists’ group “Art Abstrait” in 1956. Vandenbranden worked completely in a geometrically abstract fashion from 1954 on and practised this visual language consistently until his death in 2014. Around 1958, Vandenbranden worked in black and white mainly, his artworks almost evolving to monochromy and there was a clear connection with the work of the American Hard Edge of that time. From 1961 onwards, Vandenbranden started working with relief and his first abstract sculptures were created. From 1967 onwards he started to spray cellulose lacquer directly on panels with the aim to create visual illusions (akin to the Op Art).
