This serving tray is approximately 6-1/2" x 13" and has a beautiful design with flower baskets. This design appears to have been stamped onto the surface, as you can make out the design faintly on the back of the piece. There are no marks on the bottom, and I don't know what material it is made of. Feel free to contact us if you have any questions, or can suggest a way to tell what it is made of. A magnet does not stick to it.
