Seller's description:

A rare and exceptional example of the work of the German manufactory, Royal Bonn, circa 1900, featuring a signature work from their prestigious "Ruysdael" line. Named after the 17th century Dutch landscape painter, Jacob van Ruysdael, this line was the result of Royal Bonn's concern over their ability to compete against the likes of Royal Copenhagen, Bing & Grondahl and Sevres at the upcoming 1900 Universalle Exposition in Paris. After enlisting the talents of multiple German ceramic technicians, Royal Bonn produced the Ruysdael line.......specifically for the Exposition. The result was a gold medal. This work exhibits a double-gourd form with architectonic tendrils scaling the sides and encircling the mouth. The decoration is a luxurious tour-de-force of Jugendstil stylings involving hand-painted whiplashed vines and raised florals in enamel-thick glaze tones of golden-yellow, evening-blue, red rust-brown, milk-white and turquoise against an underglaze of olive. Signed as shown. Approx. 8 1/4" X 7"
