In a 1950 letter to London based art dealer Paul Wengraf, from whom she often purchased artworks, Mrs. Cummer decribes where she has hung some of her paintings:
“In my library are some of my dearest things […] On the right of this picture [1] is a painting of a French interior by Pauline Vallayer-Moutet.[2] This is a canvas of almost the exact size of the Morland. [3] The subject portrays two maids polishing the brasses, as only the French can do, and the strong light from a window, such as Vermeer would use in his pictures, streams into the room. And this, by the way, was my first investment in painting (the Paul King picture having been earlier acquired as a gift), and was purchased about 1905, nearly fifty years ago.”
