Gwyther Irwin was a British abstract artist who lived much of his life in North Cornwall. Educated in Dorset, at the Goldsmiths College and at the central school of art in London. Irwin first came to prominence with exhibitions at both Gallery One and Gimple Fils in the late 1950s  and  in 1964 he represented Britain at the Venice Bienalle. Gwyther is best known for his assemblages often newsprint or fragments of advertisements which he collected from the streets with his wife and which he then worked into collages combining elements of Art Brut and Abstract Expressionism. 

These works much like the piece 'Synchro' play with subtle shifts of colour and form, blurring defined lines and creating a compostion of subtle form and colour. Synchro is unusuall both in its size and the fact that it is a more traditional painting of oil and canvas, that said it has a great deal more in common with the Op-Artists who were just starting to come to promenance at this time such as Bridgette Riley.
