AI Item Analysis

·AI can make mistakes·Verify before acting
This item is a limited-edition color lithograph by the renowned American artist Alexander Calder (1898–1976), titled 'Construction' (also known as 'Composition'). The artwork features Calder’s signature mid-century modernist aesthetic, characterized by bold, primary-colored geometric shapes—specifically circles in red and blue—and sharp, black linear elements set against a cream-colored or off-white background. The composition is dynamic, suggesting kinetic energy similar to his famous mobiles. The piece is hand-signed in pencil by Calder in the lower right margin and is numbered 57/100 in the lower left, indicating a relatively low and desirable edition size. The lithograph is printed on heavy-weight artist paper and is housed in a simple, thin gold-tone metal frame. Regarding condition, there is visible 'waving' or cockling of the paper, likely due to humidity or improper mounting, which indicates it may not be on acid-free backing. There appear to be minor surface abrasions on the frame and potential light-strike fading typical of displays without UV-protective glass. A distinct horizontal reflection and a white curved line are visible in the photograph, though these appear to be external reflections on the glazing rather than damage to the print itself. The piece likely dates to the 1960s or early 1970s, a peak period for Calder’s graphic works.

AI Appraisal Report

·AI can make mistakes·Verify before acting
Based on my visual examination of this lithograph, I identify it as a work by Alexander Calder, likely dating to the late 1960s or early 1970s, titled 'Construction' or 'Composition.' The signature in the lower right appears consistent with Calder's distinctive pencil autograph, and the edition number 57/100 places it within a desirable, limited run. The kinetic energy of the composition, utilizing his trademark primary colors and geometric forms, is highly representative of his celebrated mid-century output. However, the valuation is tempered heavily by condition issues visible in the images. The most significant concern is the pronounced 'cockling' or waving of the paper. This undulation suggests the artwork has been subject to humidity fluctuations or, more concerningly, is not mounted on archival, acid-free backing. This often necessitates conservation work, including un-framing and flattening, which can be costly. Furthermore, potential light fading and frame abrasions reduce the immediate marketability without restoration. While the reflection on the glass obscures some details, the paper integrity appears otherwise intact. In the current market, pristine Calder lithographs from this era and edition size often fetch between $3,000 and $5,000 at auction. Given the condition issues requiring professional remediation, I have adjusted the value downward to the $1,500–$2,500 range. Please note: This appraisal is based solely on digital images. Without physical inspection, I cannot definitively confirm the paper quality (e.g., Arches or Rives BFK) or rule out that this is an offset reproduction rather than a true stone lithograph. Authenticity is presumed based on visual markers, but definitive verification would require removing the print from the frame to examine the edges for a deckle, watermarks, or plate marks.
