Monochrome painting bearing signature 'XETRA'

This rectangular monochrome artwork is rendered in shades of black, white, and grey, depicting a surreal or abstract subject featuring organic shapes alongside a rendering of a vintage telephone receiver and headset apparatus. The overall visual style suggests a mid-to-late 20th-century or contemporary illustrative aesthetic. Text printed at the bottom reads 'Glad to hear we're communicating.' inverted relative to the primary orientation, while a signature at the top reads 'XETRA'. The painting displays visible surface texture consistent with acrylic or oil on canvas or heavy paper, though precise medium and dimensions cannot be determined from the photographic evidence alone. There are no obvious signs of major damage, cracking, or severe wear, though the lighting causes some glare across the surface. The identification of the artist rests entirely upon the visible uppercase signature 'XETRA' located near the top edge, which is unverified and requires physical inspection to determine its nature and whether it is contemporary to the execution of the work.

Based on what I can see in the provided photograph, this rectangular monochrome painting features a surreal or abstract composition rendered in black, white, and grey, incorporating organic shapes and a vintage telephone receiver alongside the inverted text 'Glad to hear we're communicating.' The work bears an uppercase signature 'XETRA' near the top edge. I can't verify from a photo whether the signature is contemporary to the execution of the work or whether the materials are acrylic or oil on canvas versus heavy paper. Physical inspection would be needed to confirm the exact medium, dimensions, surface texture, and the nature of the signature. My appraisal estimate of $1,000 to $2,500 assumes the work is correctly attributed to the artist bearing the signature and that it is in good overall condition as suggested by the visual evidence. General market demand for mid-to-late 20th-century and contemporary monochrome or abstract works of this scale typically falls within this moderate range, depending on current buyer interest in illustrative surrealism. To confirm authenticity and solidify the attribution, an in-person examination by a qualified fine art specialist, detailed provenance documentation, and potentially stylistic or material analysis would be required. If further physical inspection reveals the item to be a reproduction, a copy, or merely in the style of the named artist rather than an autograph work, the market value would decrease significantly, typically dropping to a decorative value range of $150 to $350.
