Partially Obscured Artwork Signature and Date

The item appears to be a detail photograph focusing on the lower-left or lower-right corner of what is likely a painting or print, specifically highlighting a signature and possibly a date. The background consists of dark, likely painted, surfaces in tones of deep blue, black, and hints of muted brown or red, suggesting a rich, perhaps somber, color palette for the full artwork. A horizontal band of lighter color, possibly gold or ochre, separates the main dark background from a slightly lighter, perhaps matted, area at the very bottom, indicating the edges of a framed piece. The signature itself is applied in a lighter, likely white or light-colored paint, contrasting sharply with the dark background. The top line of the signature is somewhat clearer, appearing to read "Z. Sparro..." or "Z. Sparror..." with the subsequent letters largely indecipherable due to blurriness and potentially degradation of the paint. Directly below this, a second line of text is even more obscured but seems to contain numerical or textual characters, possibly indicating a date like "19xx" or similar, with the last two digits being "xx" or "xx" due to the extreme lack of clarity. The texture of the dark background suggests a canvas or textured paper, with some visible 'pixellation' or digital noise hinting at a lower-resolution image capture rather than inherent texture of the artwork itself. There are small specks of lighter debris or inclusions visible on the surface, which could be dust, paint loss, or minor damage. The overall impression is that of an older piece, potentially from the late 19th or 20th century, given the style of what can be discerned from the signature. The craftsmanship of the signature itself appears to be hand-painted, indicative of an original work rather than a reproduction.
