Art Nouveau porcelain demitasse

We have lots of china that are art items on its one. I am deluded because all the items I had posted before were recategorized as simply “China & dinnerware” by CW, and some of them are really important pieces like a big platter and a Meissen tea cup (http://www.collectorsweekly.com/stories/132100-a-museum-quality-art-nouveau-platter-mar, http://www.collectorsweekly.com/stories/142315-meissen-cup-about-1875) another reason of my delusion is that they have a few loves. The one we are posting here was bought last December. There is no back stamp or mark which is not unusual for 19th century pieces as factories were not required to indicate country of origin until 1891. Based on the mold, the texture of and color of the porcelain, the gilded swirls and transferred floral design this is most likely from an Austria manufacturer and date to the late c. 1880's to early 1890's. The bright blue is quite uncommon. Most probably RS Prussia mold n. 43. Thanks for looking and every comment would be appreciated.
