Estimated Value

$20-$60

Small English ironstone ceramic piece marked 'Mason's Patent Ironstone China' and 'England Made for Twinings Ltd England.' The underside shows a blue printed maker's mark with a crown device, indicating a licensed or promotional production for Twinings. The body appears to be decorated in a traditional blue-and-white transferware style, likely featuring scenic or chinoiserie-inspired motifs. Mason's ironstone is known for durable, utilitarian yet decorative wares, and this example appears to be a collectible branded piece rather than a high-value antique. The glaze shows age-related crazing typical of older ironstone.
