We mentioned the Indian Watercolours exhibition at the Wallace Collection on the Letter. And although a visit is memorable, probably essential for anyone who’s ever been to India, the catalogue is superb and would make a wonderful present. This is our favourite painting: it’s an ‘artist portrait’ c 1832-5. The catalogue says: ‘it brings us closer than any other surviving evidence to the way the forgotten Indian masters celebrated in the exhibition actually worked.’ This is an understatement: you feel you are there, you understand how they worked, this (presumably self) portrait illuminates every single watercolour in the show. Every detail is perfect and unforgettable, from the paint boxes to his glasses to the cushion behind his back.
