A painting by famous 18th-century Scottish artist Katherine Read has been discovered and authenticated - and is thought to be worth more than £100,000. The portrait features an Indian woman in a formal pose, wearing a string of pearls, a large emerald pendant, and a nose ring. Mary-Louise Wedderburn's portrait thought to have been painted by a famous relative - 18th century Scottish artist, Katherine Read. On the basis of all the evidence put together, I am entirely certain that this painting is by Katherine Read." It's just so important to me that it's by Katherine Read, because of the family connection, but also because of who she was.
