Vintage Chinese Wanyu Blue Handpainted RICE GRAIN Creamer Sugar Bowl Signed

Description

This listing is for a pair of vintage Chinese porcelain sugar bowl and creamer. Likely, they were made for exporting sometime during the 20th century.
They have a rice grain pattern, semi-translucent when held up to the light. A trim of blue and gold borders a gold, red and green pattern. The rice grains are outlined in red. This should all be painted by hand. The bottom of each item is marked "Wan Yu", a marking only used prior to the 60s, most commonly in the 20-30s, and 50s.
They have been in our family since my grandmother's time.
They look like new and it seems like they've never been used.
They have no chips and cracks and are in very excellent condition.
The creamer measures 3" high x 7" (handle to tip of the mouth). It measures 4.5" in diameter at its largest width.
The sugar bowl measures 5" high (bottom to tip of the lid),  7" (handle to handle) and 5.5" in diameter at its largest width.
The total weigh is 862g before packing.
** They are part of a complete tea set that I have just unpacked. I will be listing items in separate listings.
