This is a flow blue platter made by Ridgway's of England in the Moyune pattern. This mark and this pattern name were used beginning in 1899 and this platter would date to 1899 to 1910 when the pattern was discontinued. This pattern was created in flow blue and flow blue with added colors of pink and red in the flowers.
It has some age crazing and staining, so that reduces the value a bit. A perfect condition platter has a value of $120, in this condition $75 to $85.
