Pen and ink drawing in a sketchbook

This item is an original drawing contained across a two-page spread of a bound sketchbook, created utilizing pen, ink, and marker in a striking color palette of black, white, and a vibrant shade of orange. Based on visual observation, the artwork measures approximately sixteen by eight inches collectively across the open spread. The composition features a complex interplay of geometric color-blocked sections and dense, intricate doodling often associated with contemporary lowbrow art, zentangle, or psychedelic illustrative styles. The upper page contains bold solid blocks of orange and dark tones, while the lower page showcases prominent semi-circular shapes resembling stylized suns or architectural forms emerging from dark horizons. Swirling, organic micro-patterns cascade down the right side of the spread, weaving through the negative space with high-contrast linework. Notable markings include text embedded within the lower right cluster that appears to read 'Fubaroo' and other small lettering, though this is treated as unverified observation rather than a confirmed artist signature. The owner provides context describing the medium as pen and ink with dimensions of sixteen by eight inches, but this user-supplied claim remains unverified. The paper stock exhibits standard notebook texture with minimal surface wear, and the overall construction displays careful application of marker and fine-liner pens. The piece lacks any formally documented provenance or official certificates of authenticity, placing it firmly in the category of contemporary, unauthenticated sketchbook art.

Based on what I can see in the provided images, this item appears to be an original two-page spread drawing executed in pen, ink, and marker, measuring approximately sixteen by eight inches. Per user submission, the piece features complex geometric color-blocking and intricate lowbrow or psychedelic patterns, with unverified text reading 'Fubaroo' in the lower right corner. I cannot verify from a photo whether the materials or the attribution are fully correct, as these visual elements would need physical inspection to confirm. My value estimate of $150 to $300 assumes the work is an original sketchbook piece by the creator associated with this style. General market demand for contemporary, unauthenticated sketchbook art is niche, typically driven by collectors of lowbrow or outsider illustration. If physical inspection reveals this piece to be a reproduction, print, or mere copy in the style of the artist rather than an autograph work, the value would decrease significantly, likely dropping to a nominal $25 to $50 range. To establish a more solid market standing, this piece would require in-person examination by a qualified expert in contemporary illustration, provenance documentation, and potential review of any underlying signatures or markings.
