This is the reverse side of a fine white porcelain plate manufactured by G.D.A. (Gerard, Dufraisseix and Abbot) in Limoges, France. The plate features a smooth, glazed white finish with a slightly recessed center well and a raised foot rim. In the center, there is a clear manufacturer's underglaze backstamp in dark green or black ink that reads 'GDA' over 'FRANCE'. This specific mark was commonly used by the G.D.A. factory between the late 19th century and the mid-20th century (approximately 1900-1941). Attached to the plate is a vintage metal spring-style wall hanger, which shows some oxidization/patina on the wire. A small pink adhesive price tag marked '.50' is present near the bottom. The porcelain itself appears to be in good structural condition without visible cracks or large chips, though there is minor soot-like surface dirt and slight wear on the unglazed part of the foot rim. The craftsmanship reflects the high standards of Limoges production, known for its translucent and pure white paste.

I have examined the digital image of the plate's reverse. The 'GDA FRANCE' backstamp confirms production by Gérard, Dufraisseix, and Abbot in Limoges between 1900 and 1941. The porcelain exhibits the characteristic bright white, translucent paste synonymous with high-quality French manufacturing. Based on this visual inspection, the item appears to be an authentic example of early 20th-century Limoges production. The condition of the porcelain body appears excellent, with no evidence of hairline fractures or glaze crazing. However, the presence of a metal spring hanger is a concern; these often hide rim chips or cause 'flea bites' to the glaze under tension. The unglazed foot rim shows expected shelf wear, and the .50-cent sticker suggests a secondary market history in low-value retail environments. The market for plain or minimally decorated Limoges blanks is currently saturated. While G.D.A. is a respected name, collector demand is heavily driven by the intricacy of the overglaze decoration (hand-painted florals or heavy gilding) on the obverse. Since the front of the plate is not visible, this valuation assumes a standard decorative pattern. Rarity is low, as these were mass-produced for the global export market. Limitation: This appraisal is based solely on digital imagery. A physical examination is required to verify the absence of 'ping' test issues (internal cracks), confirm the absence of restoration, and inspect the obverse design. Full authentication would benefit from provenance documentation or a collection history to distinguish it from similar contemporary blanks.
