The Fourth 'Book of Schemes'. Album #1, the Third Folder 1978

"The Fourth 'Book of Schemes'. Album #1, the Third Folder" is a work on paper by Ukrainian artist Valerii Lamakh, created in 1978, the year of his death. The artwork consists of geometric shapes, such as triangles, squares, and lines, which are arranged in a seemingly random but calculated pattern. The lines are of different shapes and thicknesses, and the artist used a black ink and brown paint to create the artwork on a white surface. Lamakh's artwork was often inspired by mathematics and the principles of geometry. The work is a great example of conceptual art, where the focus is on the idea behind the artwork rather than its aesthetic qualities.
