This is one of my recently purchased bargain teapots. This is a vintage 5-cup Churchill Indian Tree Blue pattern and is made in England. I'm guessing it is part of an everyday dinnerware set because it is dishwasher and microwave safe.
I have been on a recent search for inexpensive 5 to 6 cup English teapots to use while serving large groups.
A "new" teapot always makes me happy!
