Vintage Lusterware Serving Bowl - White/ Peach - Flowers- Hand Painted - Japan.  It is the white with peach variety of Lusterware décor.  Flowers are bright and vivid in color … no marring of them.  It is a relish tray, trinket bowl, anything you want to use it for.  It is marked on the back with the brown Made in Japan stamp.  There is a spot in the back (see last photo) where the molding is not perfect.  

It measures 7 1/2 inches long x 5 3/4 inches wide.
