AI Appraisal Estimate

This is a large, opulent folding fan dating from the late Victorian to early Edwardian period (circa 1890-1910). The fan features nineteen staves crafted from faux tortoiseshell, likely made of celluloid or early high-quality plastic, exhibiting a deep translucent mahogany and amber mottled effect. These staves support a dense array of long, dyed black ostrich feathers. The fan measures approximately 74cm in width when fully extended, indicating its use as a significant evening accessory for formal events or opera. Each feather is individually lashed to the tips of the staves with black thread, showing careful hand-construction. A matching faux tortoiseshell ring is attached to the pivot point, intended for a finger or ribbon attachment. The feathers appear to be in excellent condition with notable fullness and minimal shedding. The staves retain a high polish with no visible cracks or warping, although minor surface scratches consistent with aged celluloid are present. The color density of the dyed feathers remains deep and uniform, lacking the brittle texture often found in poorly stored antique plumage. This piece represents the high-fashion aesthetics of the late 19th and early 20th centuries, where monochromatic, dramatic accessories were favored. The craftsmanship of the lashing and the smooth articulation of the staves indicate a high-quality production for the period.

I have carefully examined the provided images and descriptions of this late Victorian/early Edwardian ostrich feather folding fan. Measuring 74cm, this is a 'Grand' scale accessory, typically utilized for opera or formal evening galas. The 19 staves are high-quality celluloid imitating tortoiseshell, a common and fashionable choice for the 1890–1910 period to achieve durability and style. The plumage appears exceptionally well-preserved; the black dye remains deep with no visible silvering or 'rusting,' and the fronds retain their structural integrity without the brittleness common in antique taxidermy or feathers. The hand-lashed construction suggests a boutique manufacturer rather than mass-produced theater stock. Market demand for high-fashion Victorian mourning or evening accessories remains steady, particularly among collectors of millinery and period costume. Recent auction comparables for fans of this size and condition generally fall within the £150 to £300 range. The value is bolstered by the presence of the original finger ring and the lack of visible damage to the pivot pin. However, photographic analysis has limitations. Without a physical inspection, I cannot definitively confirm if the material is celluloid or a superior horn without a 'hot needle' test or olfactory check for camphor. Furthermore, while the feathers appear supple, an in-person examination would be required to rule out infestation by clothes moths or structural fatigue in the silk lashing. Provenance regarding the original owner or the original box would significantly increase the upper-end valuation. This appraisal assumes the staves are free of hairline fractures at the pivot, which is a common failure point for this material.
