Description of the Artwork
This abstract painting allegedly made in 1949 by Jackson Pollock (Attributed to) and titled "Number 1", presents a quintessential example of the dynamic and energetic "drip" style often associated with Pollock's work. This painting features an all-over, multi-layered composition, extending to the very edges of a roughly rectangular canvas measuring approximately 24 inches by 33 inches. Spanning the entirety of the picture plane, interlaced skeins of paint form an all-over composition that pulls the viewer into a la

Details
The surface is covered with overlapping networks of poured, dripped, and splattered paint, creating an intricate matrix of lines and spatters that move dynamically across the entire front of the artwork. The palette is dominated by striking tonal contrasts, merging neutrals such as grays, whites, and blacks with vibrant oranges, yellows, and hints of blue and green. Each color application sits alongside, atop, or beneath other colors, amplifying the sense of spatial depth and rhythmic complexity characteristic of a

Stretcher and Back Side
This work is mounted on a simple wooden stretcher that supports the roughly rectangular canvas, which measures approximately 24 inches by 33 inches. The stretcher construction features two horizontal bars and one vertical crossbar, providing structural integrity while maintaining a relatively lightweight framework. Along the edges, residual paint drips and spatters are visible, indicating that the painting process extended beyond the frontal surface onto the sides of the canvas and stretcher.

Signature Irregularities
Another notable point of contention is the signature that appears on the front (and purportedly references "Jackson Pollock"). Close examination reveals multiple inconsistencies when compared to documented Pollock signatures: Discontinuous Stroke in the "P": The letter "P" in "Pollock" is formed with two distinct strokes, creating a break at the top loop—a feature not observed in authentic examples, where Pollock typically executed the letter in a more continuous motion. Formation of the Letter "a": Instead of a fl

Additional Texture Concerns
Beyond the issues of canvas dimensions, signatures, and overall compositional approach, there are also notable inconsistencies in surface texture when comparing the disputed painting (A1) with known authentic Pollock drip pieces. Authentic Pollock works often exhibit what can be described as a "continuous topography" of layered paint: drips, splatters, and skeins that form subtle elevations and depressions as they overlap. These layers tend to integrate harmoniously, revealing a sense of accumulation that has taken
