It is Duchess china and the pattern is called Greensleeves. I love the colors o green and apricot together and this pattern is very delicate -- not even quite as bright as in the picture.
Well I was visiting over at Heart Shaped (click on the link) and she was telling on her blog about their village sale. She showed some photos of what she was selling.
This is Heart Shaped's photo which she kindly allowed me to use. Now look in the center of the picture -- the little jug and cup and saucer -- "Greensleeves". Sadly I was too late. They've been sold. They were only 50p each and I paid 12 pounds for my one mug!! Oh well, maybe another day.
