This is Sonia Delauney at Bielefeld, in 1958.
The square is taken from a leaflet for a wonderful exhibition at Tate Modern in 2015. My favourite exhibit, by far, was a blanket she stitched for her son Charles, in 1911. I have wanted to attempt a recreation of this blanket ever since, but so far have not found the time.

This is the sixth patch of my ‘London Exhibition Patchwork’. It is a patchwork made from leaflets of exhibitions I have visited in London. There are sixteen squares in total.
