Aramis Antiques has dated this piece to the 1800s.
The jug is profusely decorated with colourful handpainted chinoiserie scenes including a frieze around the inner and outer neck and spout. The handle too is decorated with a line of orange fruits and leaves. The jug is so pretty and seems to be in amazingly good condition for its age, a 200 year old survivor. There is a tiny hairline crack just inside the spout. A small identification card is included, presumably researched by the previous owner.
