Subject Description
A circular monochrome form in International Klein Blue (IKB). The composition consists of two semicircular lobes separated by a narrow horizontal gap, joined at a central point, resembling a tactile, cellular, or planetary shape. The work focuses on the spiritual and physical density of color rather than representational subject matter.
Condition & Value Assessment
Condition Assessment
Excellent. The surface appears matte and velvety, consistent with the artist's intention to preserve the luminescence of raw pigment.
Estimated Market Value
$5,000,000 - $15,000,000 USD
Auction Estimate
$6,000,000 - $10,000,000 USD
Provenance History
Likely sourced from the artist's estate or a gallery specializing in postwar European avant-garde (e.g., Galerie Iris Clert). Estimated history includes private European collections and major contemporary art institutions.
Art Historical Significance
A defining example of Klein's quest for 'The Void' and the 'immaterial.' This piece represents his development of International Klein Blue (IKB) and the transition from square monochromes to more organic, relief-like shapes known as 'Monogolds' or 'Monochromes' with sculptural depth.
Notable Features
Features the signature textured 'sponge-like' or velvety surface characteristic of Klein's patented IKB medium; the 'biomorphic' circular split is a rarer variation of his typical rectangular monochromes.
Condition Issues
Potential for minor pigment shedding or 'blooming' if handled improperly; highly sensitive to fingerprints and surface abrasions due to the unvarnished matte nature of the pigment.
Conservation Recommendations
Must be displayed behind UV-protective museum glass or in a strictly controlled dust-free environment. Do not touch the surface, as the oils from skin permanently mar the pigment. Maintain stable humidity to prevent the resin from becoming brittle.
