The Dublin-born Martin Craig-Martin RA returned to London from a year's sabbatical in New York in 1982 when he started to make his three-dimensional wall 'drawings' that were actually made of steel. Glasses (1987), he said, ''generalises the object, gives it [a] diagrammatic quality…I want my pictures of objects to look as much like unadulterated facts as the objects themselves.” In the early 1960s Craig-Martin also spent five years teaching at Yale School of Art and had been immersed in Pop art, Mimimalism, Conceptual art as well as the music, design and architecture of that time in the USA. Glasses was made before he turned to 'big colour' in his artworks that he is best known for today.
