Mixed media portrait signed 'Daiana Vaiani'

This artwork is a vivid figurative portrait depicting a human face rendered in a rich, expressive color palette of blues, oranges, yellows, reds, and deep blacks. The medium appears to be oil pastel or heavy chalk on a textured, off-white or cream-colored art paper with visible deckle edges. The subject features striking, wide green eyes, a defined nose, and bright red lips showing hints of teeth. The application of pigment is heavy and layered, creating a textured surface with visible strokes and blending, characteristic of an expressionist style. The piece is housed behind glass in a minimalist clip-frame featuring a bold red mat board border held together by small metal clips. At the lower right corner of the composition, there is a visible handwritten signature that reads 'Daiana Vaiani' along with a small initial or line below it. The attribution in the name rests directly on this legible signature. The overall physical condition appears well-preserved within its modern clip-frame, though the artwork itself remains unauthenticated and is evaluated solely based on visible visual evidence.

Based on what I can see in the photograph, this work on paper is a vibrant mixed media portrait bearing a signature that reads 'Daiana Vaiani'. The heavy pigment application, expressive color palette, and textured paper suggest an expressionist aesthetic. However, I can't verify from a photo whether the materials are archival or if the signature is contemporaneous and by the artist's own hand. My value estimate of $600 to $900 assumes that the attribution to Daiana Vaiani is correct. Works of this scale and type by contemporary emerging or mid-career artists generally trade within this bracket in current secondary art markets, depending on gallery representation and exhibition history. That said, this valuation is purely conditional; an unauthenticated piece or a decorative copy 'in the style of' would command a significantly lower decorative value, likely in the $100 to $250 range. To establish a higher level of confidence in the attribution, I would need physical inspection to confirm medium characteristics, paper age, and signature details, alongside provenance documentation or consultation with a recognized authority on the artist's oeuvre.
