This beautiful dish is in the pattern Blue Bouquet by Noritake #6735.  A rare find, this divided vegetable bowl is 10 inches long x 7 inches wide and 2.5 inches in depth, and says Cook n Serve on the back.  The Blue Bouquet pattern was produced from 1966 to 1971, then discontinued.  This dish is in great condition with no chips or cracks, but some slight wear on the bottom.
