This was one of my grandmother's favourite paintings. It's by Kate Greenaway . When I was a teenager she sent me a card with this painting and said Tea at High House.
Grandma grew up at High House and she just loved it. The house is still there with the same name. It sits up high on a hill. Either side of the front door are bay windows that go from ground to roof, two stories. So I can just imagine grandma having tea on the lawn like this.
