Abstract mixed media painting attributed to Lister

This is a large-format abstract composition on canvas, enclosed in a thin, gold-toned metal or metallic-finished wood frame. The work features a complex layering of earth tones, including ochre, burnt sienna, cream, and deep charcoal, with translucent glazes and opaque impasto. Stylistically, the piece appears consistent with contemporary abstract expressionism, utilizing horizontal gestural strokes and dripped paint effects. The owner identifies the artist as 'Lister', and a signature reading 'LISTER' in white uppercase lettering is visible in the upper right quadrant of the composition; however, this attribution remains a hypothesis subject to physical inspection and professional authentication. Intricate, fine-lined white markings resembling shorthand or geometric sketches are overlaid across the darker central masses. The canvas shows a visible pebble-like texture under the paint, suggesting either a heavy-duty cotton duck or a prepared texture medium. The condition appears stable, with no obvious signs of flaking, moisture damage, or significant fading visible in the photo, though some minor surface dust and typical handling marks on the frame edge are present. The artwork's vertical orientation and layered depth suggest a late 20th to early 21st-century production period.

Based on my examination of the provided photograph, this is a large-format mixed-media abstract expressionist painting. The work bears a signature in the upper right quadrant reading 'LISTER'. Per the user submission, the piece is attributed to an artist named Lister. Based on what I can see, the composition utilizes a sophisticated palette of earth tones with gestural markings and translucent glazes characteristic of late 20th or early 21st-century contemporary art. The value estimate is based on the assumption that the attribution is accurate. In the current decorative and contemporary art market, works of this scale and aesthetic appeal typically command between $800 and $1,500. However, I cannot verify the medium, substrate, or authorship from a photo. I cannot confirm if the 'LISTER' signature is integral to the paint layer or a later addition. The value is highly dependent on authentication; if the piece were determined to be an unattributed work 'in the style of' or a reproduction, the market value would likely decrease to a decorative range of $200 to $400. To establish a formal identification, a physical inspection is required to examine the canvas weave, paint chemistry, and any labels on the reverse. Provenance documentation or a gallery bill of sale would also be necessary to support the owner's attribution. Because this evaluation is based solely on a digital image, it does not constitute a guarantee of authorship or a legal valuation of authenticity.
