Color etching, aquatint, and carborundum on Arches woven paper. Techniques include multi-plate printing, spit-bite aquatint for the color gradients, and embossed line work.
Creation Period
1971
Dimensions & Format
Approximately 65 x 50 cm (sheet size); Portrait format
Subject Description
A complex 'inscape' depicting cosmic landscapes and biomechanical figures. The composition features Matta's signature 'morphologies' where skeletal, wire-like figures interact with geometric structures and energetic vortices. The narrative suggests a psychedelic or inner-psychological map of the universe.
Condition & Value Assessment
Condition Assessment
Very Good. The paper appears bright with strong ink saturation. Margins are intact with visible edition numbering and signature.
Estimated Market Value
USD 1,500 - USD 2,500
Auction Estimate
USD 1,200 - USD 1,800
Provenance History
Likely part of a dispersed portfolio published by Editions Sonet, Sweden. Numbers in the '54/100' range suggest a standard limited edition distribution through fine art galleries.
Art Historical Significance
Matta was a pivotal figure in bridging European Surrealism with American Abstract Expressionism. This work, from his later period, demonstrates his mastery of printmaking and his lifelong obsession with the 'fourth dimension' and the representation of psychological space.
Notable Features
Includes a visible hand-signature in pencil by the artist in the lower right and edition number '54/100' in the lower left. The use of carborundum creates a distinct textural relief and deep velvety blacks characteristic of Matta's late graphic work.
Condition Issues
Minor edge wear consistent with age; potential for light acidification if previously framed with non-archival materials, though none is visible in the primary image.
Conservation Recommendations
Should be mounted using acid-free, reversible hinges and protected by UV-filtering glass to prevent the vibrant green and yellow inks from fading.
