Kim Tcha-sup: Ida, 1970. Kim's painting presented a dirt ground upon which objects–reminiscent of tools and waste materials disposed at construction sites–together compose a humanoid figure. Lee Seung Jio: Nucleus G-111A (핵 G-111A), 1970. Lee presented a geometric abstract painting from his Nucleus series. The repeated achromatic lines at varying shades seemed to render three-dimensional cylinders stacked together, offering a peculiar combination between a two-dimensional plane with a three-dimensional illusion. This marked the official debut of Lee's “pipes.” Lee Seungteak (이승택, 1932–): 1970, 1970. Park Chongbae: Untitled, 1970. 36 Park Suk-Won: Handle 707, 1970.
