“Tree, large blue sponge” is an artwork created by Yves Klein in 1962. The piece is part of the Nouveau Réalisme art movement and falls within the sculpture genre. It is also part of the “Multiples” series.
The artwork features a structure that resembles a tree, crafted in Yves Klein’s signature International Klein Blue (IKB). The ‘tree’ trunk is slender and irregular, leading up to a large, sponge-like form perched atop. The vivid blue color emphasizes both the texture and the abstract form of the sculpture. The base appears to merge organically with the trunk, suggesting a seamless integration with the ground upon which it stands. This particular piece demonstrates Klein’s fascination with texture, form, and his innovative use of monochromatic palettes.
