"Royal Copenhagen, officially the Royal Porcelain Factory (Danish: Den Kongelige Porcelænsfabrik), is a Danish manufacturer of porcelain products and was founded in Copenhagen in 1775 under the protection of Danish Dowager Queen Juliane Marie. It is recognized by its factory mark, the three wavy lines above each other, symbolizing Denmark’s three straits: Storebælt, Lillebælt and Øresund." - (en.wikipedia.org 24.03.2020)
