Art Deco-style banded ceramic vase

This ceramic vase features a conical form tapering down to a stepped, circular pedestal base. The body is decorated with a series of horizontal concentric ribs, or annular rings, which provide a textured surface throughout. The glaze application consists of distinct horizontal color bands: a wide sky-blue band at the top rim, a narrow brown transition line, a creamy off-white central section, and a golden-ochre or honey-colored base. The interior appears to be finished in a solid blue glaze. This banded, geometric aesthetic is stylistically consistent with British Art Deco pottery from the 1930s. The owner identifies this piece as 'Shelley England 975', which would attribute it to the Shelley Potteries; however, since no maker's mark or 'Shelley' backstamp is visible in the provided image, this attribution remains unverified and subject to physical inspection. The craftsmanship appears consistent with mid-range decorative earthenware or bone china of the early 20th century. No significant chips, cracks, or heavy crazing are immediately apparent in the photo, though minor surface wear to the glaze may be present upon close examination.

I have examined the images of this Art Deco-style banded ceramic vase. Per the user's submission, the piece is attributed to Shelley Potteries of England, specifically pattern/shape 975. Based on what I can see, the conical form with horizontal annular rings and transitional color banding is stylistically consistent with British earthenware produced during the 1930s. However, because no maker's mark or backstamp is visible in the provided photos, I cannot verify the origin from an image alone. The value estimate is predicated on the assumption that the piece bears the maker's mark described by the owner. If the attribution is correct and the piece is an actual Shelley Potteries product in excellent condition, the market value typically falls within the $150 to $250 range. This estimate reflects the continued interest in Art Deco ceramics, though demand fluctuates based on the rarity of the specific colorway and shape. This valuation would decrease significantly, likely to $40-$60, if the item is found to be ‘in the style of’ or a later reproduction without a verifiable mark. Physical inspection by a specialist is required to examine the glaze for micro-crazing and to confirm the existence of the 'Shelley England' mark on the base. Provenance documentation or scientific testing of the clay body would further support the age. Until such an in-person examination occurs, this attribution remains a hypothesis. The craftsmanship appears competent, showing no immediate signs of chips, but surface wear can often be hidden by photographic glare and would need to be checked in person.
