Here is a collectible little shoe from the famous Koninklijke Royal Delft, De Porceleyne Fles. Delvert is the name of pieces decorated with a soft green or slight blue-green color designed by the famous Herman Sanders. It was only produced from 1968-1976 and 1991-1994.
It measures almost 2-3/4 inches tall and 4-1/4 inches long and 1-1/2 inches wide. On the bottom are the typical marks of the date code, painter's marks and model number. In excellent condition with a little wear on the bottom.
Resources: The details included in this listing are based on information from Rick Erickson's highly regarded book Royal Delft: A Guide to De Porceleyne Fles.
I appreciate and thank you for taking the time to look. Have a wonderful day. .
