Marks: The “BP” mark in underglaze blue used in the 18th century at De Vergulde Bloempot. It is marked on the reverse with the initials “BP” identifying it as a work of this distinguished maker. The mark is smudged as can be seen in the relevant photographs but is beneath the final glaze.
This product would be a great fit for collectors of Dutch ceramics with an interest in 18th-century history or art.
