L.S. & S. Carlsbad Austrian Porcelain Maker's Mark

This is a detailed image of a ceramic backstamp or maker's mark located on the underside of a porcelain item. The mark is applied in a cobalt blue underglaze and features a circular arrangement of text. The inscription reads ‘L.S. & S.’ at the top, followed by ‘CARLSBAD’ and ‘AUSTRIA’ at the bottom. This specific mark is attributed to Lewis Straus & Sons, an American importing firm based in New York that commissioned high-quality porcelain from various factories in the Carlsbad region of Bohemia (then part of the Austro-Hungarian Empire, now Karlovy Vary, Czech Republic). The porcelain itself appears as a bright, clean white translucent body, indicative of fine Vitrified ceramic material popular in the late 19th and early 20th centuries. The mark's typeface and circular composition suggest a manufacturing date between approximately 1895 and 1917. The condition of the glaze over the mark is smooth with a high-gloss finish, though there are minor dark specks (firing dots) and some light surface abrasions consistent with age and shelf wear. The stamp is slightly faded or incompletely transferred on the right side of the circle, a common occurrence in manual stamping processes of that era. This marking serves as a significant indicator of provenance for collectors of European export porcelain.
