Modern colorful mixed-media artwork in a style consistent with Corneille

This item is an unframed work on paper, currently displayed within a larger glazed frame. The piece features a vibrant, multi-layered composition incorporating bold primary and secondary colors including sky blue, deep red, yellow, and black. Stylistically, the item is consistent with the CoBrA movement, specifically exhibiting motifs such as stylized birds, organic floral forms with thick black outlines, and whimsical, childlike figures. The background features a mottled, textured blue field that resembles a lithographic or screen-printed process. Notably, the bottom right corner of the blue section bears a cursive signature that appears to read 'Corneille.' However, without physical inspection, this signature cannot be used to declare the work an original Guillaume Cornelis van Beverloo piece as signatures can be replicated. The paper has a visible deckle edge on the right side, suggesting it may be a hand-pulled print or a high-quality artist paper. The work is held behind glass in a dark, possibly marbled-effect frame. Visible condition includes some slight buckling of the paper substrate, which is a common characteristic of works on paper, and some dust or particulates on the interior glass surface. This attribution remains a hypothesis subject to professional in-person authentication.

I have examined the digital image of this mixed-media work on paper, which exhibits stylistic characteristics and a signature consistent with the Dutch CoBrA movement artist Guillaume Cornelis van Beverloo, known as Corneille. Based on what I can see, the composition features the bold, whimsical iconography of birds and floral motifs that are hallmarks of his late-career aesthetic. The presence of a deckle edge and the texture of the blue field suggest a high-quality lithograph or screen-print, though I cannot determine from a photo if this is a hand-embellished print or a unique work. The value of $1,000 to $2,500 is based on the working hypothesis that this is a legitimate numbered print or work by the artist. This estimate reflects the healthy secondary market for CoBrA-affiliated art, where vibrant, large-scale compositions are generally in higher demand. However, this estimate is contingent upon physical inspection. Without examining the paper’s watermark, the specific application of the ink, or examining the verso for edition numbers, it is impossible to exclude the possibility of a high-quality contemporary reproduction. I cannot verify authorship or the state of the signature through a photograph alone, as markings can be replicated. If this item were found to be a posthumous reproduction or a decorative piece 'in the style of' the artist, the value would likely drop to a decorative range of $100 to $300. To establish a more precise valuation, a professional in-person examination by a fine art specialist is required to verify the printing technique and search for documented provenance or inclusion in a catalogue raisonné.
