Pen and Ink Lighthouse Illustration in Spiral Sketchbook

This item is an original illustrative drawing of a lighthouse coastal scene, executed in black ink on off-white or cream-colored paper. The artwork is contained within a portrait-oriented, side-bound spiral sketchbook featuring a black plastic or metal double-coil binding. The drawing displays a central, multi-tiered lighthouse structure perched atop jagged rock formations, surrounded by billowing cloud-like forms and a horizontal representation of water in the foreground. The technique utilizes varying densities of cross-hatching, vertical line work, and solid black fills to create contrast, depth, and texture. Notable features include a stylized signature in the lower right corner that appears to read 'Yohann'. The composition suggests a contemporary amateur or student-level work, given the pen-based hatching styles and the medium. The paper shows slight texture and the ink appears to be from a fine-liner or technical pen, similar to the Hauser Germany pen seen resting adjacent to the book. The condition is excellent with no visible tears or significant smudging, though the sketchbook pages show standard minor edge wear consistent with handling. The overall aesthetic is monochromatic and leans toward a graphic, illustrative style often found in personal art journals or concept sketches.

I have carefully examined the provided digital image of the original pen and ink illustration entitled 'Lighthouse Coastal Scene,' attributed to the artist signing as 'Yohann.' The work is executed in a technical fine-liner medium within a standard spiral-bound sketchbook. My visual assessment confirms the piece is in excellent condition, with crisp ink saturation and no visible foxing, light-strike, or mechanical damage to the paper. The technique displays a proficient grasp of graphic cross-hatching and value contrast, characteristic of high-quality student or contemporary amateur illustration. The market for original sketchbook art by unlisted or emerging artists typically commands a decorative value. Comparables for similar ink architectural/nautical studies on contemporary paper stocks generally fall within the double-digit range. The rarity is limited as it is a personal sketchbook entry rather than a formal, exhibited, or numbered work. The primary value drivers are the aesthetic appeal and the 'Yohann' signature, though the artist's professional profile remains unidentified in major auction databases. It is important to note that this appraisal is based solely on digital images. A physical inspection is required to confirm the paper's GSM, the acidity of the cream-toned stock, and to ensure the ink is indeed hand-applied rather than a high-quality giclée reproduction. Specifically, I would need to observe the 'bite' of the pen nib into the paper fibers under magnification. Verification of provenance or the artist’s identity via a curriculum vitae or sales history would be necessary to justify a higher valuation.
