Art Nouveau Antiques for Sale.
The art nouveau style literaly means new art and gets its name from a design shop, La Maison de l'Art Nouveau, which German entrepreneur Siegfried Bing opened in Paris in 1895. 
The art nouveau designers rejected the inspiration of classical european art and instead looked to Japanese, Celtic and other folk art as a basis for their work. This can be seen in works by artists such as Gustav Klimt. Typical motifs come from nature: flowers, insects and birds. Lines curve and wind, straight lines were scorned by art nouveau designers.
Watching the experts at antique roadshows, you probably wonder just how they get so much information about an antique simply by turning the item upside down.
The Victorian Design Registration Mark or Kite Mark was used between the years 1842 and 1883.
