An antique Villeroy & Boch washbasin (wash bowl) from the "Erft" line. This model is characterized by the distinctive Art Nouveau (Jugendstil) style of the early 20th century. It features a distinctive red sprayed decoration (*roter Sprühdekor*) and a gold rim along the wavy edge. XXXL size The image shows a historical mark used by Villeroy & Boch for products from their factory in Mettlach, Germany. In collector circles, this specific mark is known as the "Mercury mark." It depicts the head of the Roman god Mercury (the god of commerce) wearing a winged cap, flanked by two caducei (staffs entwined with snakes), with the company name on a central ribbon and the factory location inscribed in a semi-circle. Key details about the mark: Period of use: This type of mark was primarily used between 1874 and 1909. Application technique: It is a printed (stamped) mark, most commonly applied in green (as shown in the image), though it can also be found—albeit less frequently—in blue, black, or brown. Craquelure effect: Pronounced fine cracks in the glaze surrounding the mark (known as *craquelure*) are a common occurrence and a natural sign of aging on older ceramics and semi-porcelain from that era.
