This second look at Doulton’s Persianware is solely focused on seriesware. There are three variations of this ware, A, B and C. The first designs were introduced around 1912 with a white background. This would be replaced in 1917 with a blue background.
This pattern of course has a special backstamp as shown here.
Typically of Doulton’s seriesware unusual items turn up from time to time. Only yesterday I saw a hat pin stand in this pattern. Other items that have turned up range from usual Doulton style vases to dressing table sets to tea sets.
