In 1962, Lee Seung-jo, who formed an avant-garde group called 'Origin' in opposition to the existing art system and vested interests with fellow painters, sought a return to the 'original thing' and built a unique formative language. Since the late 1960s, the shape of a 'pipe' has appeared in his works, and this motif, which creates a visual illusion by changing simple shapes and colors in a strict order, has been used as the main language. In this solo exhibition of Lee Seung-jo, held for the first time at Kukje Gallery, about 30 major works, focusing on the representative pipe-shaped works, will be introduced that look at the strong visual language.
