Ceramic Saucer with 'Art Gallery' Maker's Mark

The item appears to be the underside of a small, white, circular ceramic or porcelain piece, likely a cup saucer or a small plate, due to its flat, raised center and slightly concave form. Its physical characteristics include a smooth, glossy white glaze, typical of modern dinnerware. The primary distinguishing feature is the manufacturer's mark or branding, centrally located on the underside. This mark reads "art" in a sans-serif lowercase font, with a solid black square or block beneath it that contains the word "GALLERY" in white, all-caps sans-serif lettering. The overall design of the mark suggests a contemporary aesthetic, possibly dating from the late 20th or early 21st century. There are no obvious signs of significant damage, cracks, or repairs. A small amount of what appears to be minor dirt or residue is visible along the inner edge of the raised central ring, suggesting some previous use or storage with light accumulation. The craftsmanship appears to be standard for mass-produced ceramic items, with a consistent glaze and clear, applied transfer for the maker's mark. The piece's size can only be estimated relative to the hand holding it, but it appears to be designed for a single serving or as part of a tea/coffee set. The 'Art Gallery' branding might indicate it was part of a promotional item, museum gift shop merchandise, or a line of artistic-themed tableware.
