Ancient Art Nouveau service

The porcelain set for 4 persons from Friedrich Kaestner's manufactory is designed in the Art Nouveau style, as evidenced by both the shapes of the dishes and the flower motif (cornflower thistle flowers?). Hand-drawn. Stamp in the porcelain mass. It corresponds to the production period of the Kaestner manufactory around 1900-1920. Central pieces: coffee pot (2 l), cream jug, and sugar bowl. 4 coffee duos. No signs of use.
