Overview
The underside of the cup features a clear green underglaze 'D & Co' mark. This is a well-documented factory mark used by R. Delinières & Cie of Limoges, France, specifically on whiteware blanks produced between 1879 and 1900.
Story
The porcelain blank was manufactured by R. Delinières & Cie in Limoges, France, between 1879 and 1900, as confirmed by the green underglaze factory mark. During this period, it was common practice for French factories to export undecorated 'whiteware' to be hand-painted by professional decorating studios or skilled amateur china painters. The specific artist or studio responsible for this Art Nouveau decoration remains unidentified.

Condition & Value
Based on the provided description, the set appears to be in good visual condition. However, value in delicate antique porcelain is highly dependent on the absence of microscopic flaws. Any unmentioned fleabite chips, hairline cracks along the rims, or wear to the painted enamel would significantly impact the final resale value.
Full Research
Sold comps, value drivers, and venue guidance pulled from recent auction results.
The secondary market for late 19th-century Limoges porcelain is saturated, with a strong buyer preference for complete sets or highly documented studio decorators. Single cups and saucers, especially demitasse, often trade as decorative cabinet pieces or replacement items rather than high-value collector targets. While the Art Nouveau style adds aesthetic appeal, the lack of a known decorator signature keeps prices modest.
▲ Confirmed R. Delinières & Cie underglaze mark establishes the 1879-1900 production era.
▲ Fluid, hand-painted Art Nouveau decoration appeals to period aesthetics.
▲ Matching cup and saucer pair retains more value than orphaned pieces.
▼ Unidentified decorator limits the piece to general decorative value rather than premium studio pricing.
▼ Unverified rim and handle condition — hidden hairlines or fleabites would severely discount the piece.
▼ Single demitasse sets have a limited buyer pool compared to complete tea or coffee services.
Best Venue
List on a broad online marketplace like eBay or Ruby Lane, targeting collectors of antique teacups or Art Nouveau ceramics. Ensure the listing title includes 'Delinieres Limoges', 'Art Nouveau', and 'Demitasse' to capture search traffic. Given the modest value of single cups, professional auction consignment is not recommended.
Upside Potential
If a hidden signature or decorator mark can be found and attributed to a highly sought-after professional studio (such as a premier American or European decorating house), the value could push toward the $75-$100 range for a single cup and saucer.
