Provenance History
Formerly in the collection of major American art institutions or private estates focused on mid-century modernism; likely exhibited in New York during the late 1950s.
Art Historical Significance
Ibram Lassaw was a foundational member of the American Abstract Artists group. This piece is significant for its early adoption of the 'open-work' skeletal structure, influenced by his interest in Zen Buddhism and the interconnectedness of all matter.
Notable Features
Features Lassaw's signature 'molten' texture where the bronze appears to have flowed and solidified into lace-like patterns, reflecting the spontaneity of Abstract Expressionist painting in three dimensions.
Condition Issues
Minor surface dust in deep recesses; slight oxidation (verdigris) typical of copper-alloy sculpture; tension points in the thin wire-like sections may be susceptible to bending if mishandled.
Conservation Recommendations
Regular dusting with a soft natural-hair brush; display in a climate-controlled environment with low humidity; use of archival wax coating if further oxidation occurs.
