Are these marked at all on the underside?
Thank you for the additional images. The stamp with country of origin mark indicates that this was made post 1893. The style, which is distinctly Art Nouvuea in form with the whiplash shape of the handles dates this to 1895 - 1905. The Calla Lily flower was also a decorative element of Art Nouveau. The stamp is not attributed to a specific maker, of which there were countless number there at that time. The material is porcelain, which is a mixture of kaolin and petuntse clays which are rich in that region. The floral decoration was transfer printed by hand then embellished by hand, though not painted on by freehand. On today's market, the set can sell for a high of $45 at auction. The suggested insurance or replacement value is $90 for the set. These were selling for signficantly higher a few decades ago, however the market is now currently flat on them.
