Rare antique Doulton Lambeth jug by Frank Butler 1888 excellent condition

It is typical of his unique Art Nouveau designs with a blue medallion and hearts outlined in cream enamel dots. The base is fully marked Doulton Lambeth England with Butler’s initials JAB, a painter’s initials (I assume) GP and 88 which I assume is the year of design/creation. Also stamped marks O and P. Condition is superb, there is a small area on the foot where the brown glaze is missing but this is under the top glaze so must be a manufacturing spot. It stands just over 6 tall and has a pleasing rotund shape. This is a vintage or pre-owned item so please expect some wear and tear from use. I have done my best to describe it accurately but may have overlooked some detail. Please note that the images have been enlarged to show detail. Please contact me if you have any questions.
