This is one of the oldest bowls I have ever seen and i know someone may recognize the mark. The mark is in blue and the cowl is lovely and has some cracks that are hairline but they do not go all the way through the piece. The piece is about 5 1/4 inches across the top and it sits about 1 1/8 inches tall. A very lovely and I do not know the exact age but maybe early 1800s or earlier if i were to guess. It is not perfect but not bad. Please look at the pictures. The design looks maybe transferware.
