Since 1879, each hand painted article produced by De Koninklijke Porceleyne Fles has been marked with the mark on the right. It consists of:
- – A jar

- – The City of Delft
Below to the left the painter’s initials are painted and on the right a year code. Using the year code list you can find out in which year your Delftware was produced.
