Japanese-style kakejiku (hanging scroll) attributed to Sosen

This item appears to be a Japanese kakejiku (hanging scroll) ink and color painting on a light-colored ground, likely paper or silk. The composition features a monkey in a light gray-blue patterned garment holding a reins-like implement, riding or interacting with a small white horse decorated with a red saddle cloth and a bell. The style of the monkey, particularly the fine detail in the fur and the expressive facial features, is stylistically consistent with the Mori school of the Edo period. The lower right corner bears a signature reading 'Sosen' (祖仙) and two red seal marks, which are consistent with markings used by Mori Sosen (1747–1821), a painter renowned for his depictions of monkeys. However, without physical inspection of the ink flow, silk/paper age, and seal authenticity, these markings should be viewed as a hypothesis rather than a fact. The painting is mounted on a patterned brocade borders in gold and brown tones featuring geometric and floral motifs. There are visible signs of age including minor creasing, light foxing, and some discoloration to the mounting and the painting surface. The craftsmanship appears significant, noted in the delicate rendering of the monkey's coat and the whimsical subject matter common in later Edo-period works.

I have examined the digital representation of this Japanese hanging scroll (kakejiku). Based on what I can see, the composition displays a high level of technical proficiency, particularly in the rendering of the monkey's pelage, which aligns closely with the Mori school style of the late Edo period. The work bears a signature and seals consistent with Mori Sosen (1747–1821). While the whimsical subject matter and brushwork suggest significant quality, I cannot verify the age of the silk, the depth of the ink, or the authenticity of the seals from a photograph alone. Such determinations require a physical inspection to check for 'hanko' (seal) accuracy against known registers and to ensure the pigments are period-appropriate. The valuation of $4,000 to $7,000 reflects the market for a high-quality work attributed to Sosen in fair condition, noting visible foxing and creasing which typically lowers the value. General market demand for Mori school subjects remains steady among collectors of 'Nihonga' and Edo-period painting. However, should a physical examination reveal this to be a later 19th-century copy or a 'shinsaku' (new work) in the style of Sosen, the value would likely drop to the $300 - $600 range. To confirm the attribution, I recommend a consultation with a specialist in Japanese art to evaluate the wood rollers, the mounting technique, and the potential for a documented provenance or 'box inscription' (tomobako) which is not pictured here.
