 The artist refers to this as "yohaku" or the art of emptiness.In the "From Point" works he adopted a similar method in order to produce a fading series of small, discrete, rectangular brushstokes.In 1991 Lee began his series of "Correspondance" paintings, which consist of just one or two grey-blue brushstrokes, made of a mixture of oil and crushed stone pigment, applied onto a large white surface.
