One of my favourite china patterns is Blue Willow. My everyday china has the pattern and I have accessories, teapot, jugs and sugar bowl to match; even a set of tin canisters. None of those is particularly old or especially precious, however, the one in the picture is a favourite in my collection.
I don't know how old it is , as it has no backstamp or markings. I bought it on my first trip to the UK in 2000, from an antique shop in Chester, which is a fascinating city. It has Roman remains and is surrounded by a 2000 (almost)year old wall. It is also credited with having what could be called the first shopping arcade. There are lots of half-timbered shops and dwellings in the Tudor style, but apparently they were mostly built in the Victorian era.
