Hi all just came across 3 Art Deco / Art Nouveau Tiles while going through more boxes and love them!!!! BUT I know nothing about them. any help would be great they appear to have a double connected diamond on the back. maker?? date produced??(guess 1900- 1930) value??? I need to know it all on this one. They are 6" by 6". The background is a beautiful deep green with pastel yellow, blue & green.
Thanks
