Modernist Spherical Hollow Form
Sculpture, hollow metal vessel • Anonymous modernist; style consistent with the British Studio Craft movement or American Mid-Century Modern metalworkers such as Paul Evans or Harry Bertoia (in manner)

Style & Movement
Mid-Century Modern / Brutalism
Medium & Technique
Casted or hand-raised copper with a hand-applied chemical patina; features a singular organic vertical fissure and open aperture
Creation Period
Mid to late 20th Century (circa 1950-1980)
Dimensions & Format
Approximately 8-10 inches in diameter; spherical/globular format
Subject Description
An abstract, biomorphic study of volume and void. The piece explores the contrast between the protective outer shell and the dark, recessed interior. The vertical split suggests a 'seed pod' or 'cracked earth' motif, emphasizing organic imperfection within geometric precision.
Condition & Value Assessment
Condition Assessment
Good; shows consistent surface oxidation and age-appropriate wear to the patina
Estimated Market Value
$400 - $1,200 (if non-attributed); significantly higher if a signature from a recognized artist is discovered
Auction Estimate
$300 - $800
Provenance History
Unknown; likely a private collection or acquired through a studio estate. No visible signatures or foundry marks are apparent from this angle.
Art Historical Significance
Representative of the post-war shift toward organic abstraction and the rejection of industrial perfection. It mirrors the work of Barbara Hepworth or Henry Moore in its focus on piercing the form to integrate surrounding space.
Notable Features
The irregular, hand-cut nature of the vertical 'tear' indicates a studio-crafted origin rather than mass-produced manufacturing; the warm copper tones suggest a high copper-content alloy.
Condition Issues
Minor surface scratches, uneven oxidation (verdigris) near the base of the split, and localized areas of thinning patina
Conservation Recommendations
Avoid abrasive cleaning. Light dusting with a soft cloth; if preservation is prioritized, a microcrystalline wax (e.g., Renaissance Wax) can be applied to stabilize the metal surface from further moisture-induced oxidation.
