This is an antique, hand painted, A & D Co., Limoges, France, sandwich tray. This is one of several pieces that I have listed in this pattern. It has two marks, one is A & D, Limoges, and the other is the mark for L R & R Decorators, who decorated porcelain for various companies. This mark (the star) dates this piece to 1891- 1914.
This piece is in very good condition. Take a look at the pictures, and if you have questions, please e-mail.
