Royal Bonn was a trade name used by Franz Anton Mehlem, who had a pottery in Bonn, Germany during the nineteenth-and twentieth-century. Porcelain and earthenware were the main products manufactured by Royal Bonn. In 1921, the factory was purchased by Villeroy & Boch and was subsequently closed in 1931. Numerous marks were used on these potteries, including the name "Bonn", the initials "FM," and a crown. We can see Royal Bonn Vases, bowls, plates, and jars in attractive colors.
