Large-format abstract cityscape acrylic painting

A large-format abstract expressionist composition that appears to represent a city skyline. The work is characterized by vertical, rectangular blocks of varying heights rendered in a layered impasto style. The palette is diverse, featuring prominent cool tones of slate blue, teal, and gray, punctuated by vibrant bursts of orange, magenta, and lime green. The base of the composition suggests a reflective surface, perhaps water, through horizontal dragging of paint and blurred color repetitions. Visible textures indicate the use of palette knives or wide brushes. The work bears a cursive signature in the lower right corner that appears to be written as 'Dale' in a metallic gold or bronze pigment. The user-provided claim suggests the work is by Dale Haessly and measures 150X90 cm in acrylics; however, since no secondary verification or physical labels are visible, this attribution and the specific medium remain unverified hypotheses. The condition appears stable with intentional distressing in the paint application, though fine surface scuffs cannot be ruled out without physical examination. The style is consistent with late 20th to early 21st-century contemporary abstract art.

Based on the provided imagery, I have reviewed a large-scale abstract expressionist painting featuring a rhythmic skyline composition. Per the user's submission, the work is attributed to Dale Haessly, measures 150x90 cm, and is executed in acrylics. From what I can see, the work bears a signature in the lower right corner consistent with 'Dale', though I cannot verify whether this signature was applied by the artist at the time of creation or added later. The impasto technique and layered application suggest a late 20th or early 21st-century contemporary piece. The estimate assumes the attribution provided by the owner is correct; however, without a physical inspection or a certificate of authenticity, this remains a working hypothesis. From a photo, I cannot confirm the paint medium or the substrate's structural integrity, nor can I rule out minor surface scuffs or environmental damage. General market demand for contemporary abstract cityscapes of this scale is consistent, with decorative value remaining high due to the size. If the attribution to Dale Haessly is verified through provenance or an in-person expert appraisal, the value sits in the $400 - $800 range. If the work is determined to be 'in the style of' the artist or a later copy, the value would likely drop to a decorative range of $150 - $300. To confirm the higher valuation, scientific testing of the pigments and an examination of the stretcher bars for historical labels would be required.
