From the oldest and probably the best delftware maker, De Porceleyne Fles, here is a bull often seen listed as a cow. About 4-inches tall in excellent condition with some crazing which is not unusual for older delft.. If you bought this new today, it would cost about $350.00!
The marks on the back have the Royal Delft insignia, CI for the date code of 1964. Also the painter's initials.
I appreciate and thank you for taking the time to look. Have a wonderful day. .
