Bottle JT

Belongs to: Joost Thooft

Joost Thooft, owner of De Porceleyne Fles, 1876-1884 (factory mark is still being used)

The mark - a figurative sign of a bottle and the letters JT - has been used by De Porceleyne Fles/Royal Delft since 1879. The year marks and painter's initials also provide more information about an object. In addition, the checksums or article numbers are sometimes included.

The year marks consist of one or two letters that represent the year of production. Below you can find an overview of the year marks of De Porceleyne Fles. The painter signed the piece with his or her initials. Unfortunately, not all initials have been identified, but an overview of the known signatures or initials can also be found on the website of Royal Delft (De Porceleyne Fles).

Other marks that have been used by De Porceleyne Fles or Royal Delft can be found here and here.
