On the left is the title page of the diary: in the upper half of the picture is a painting of a young woman, watercolours and black ink on slightly yellowish coloured paper. She is sitting on a cloud and is drawing in a sketch book. In the bottom half of the picture is "A London Diary" in red letters, plus the date and place it was painted.   
Right, a sketch from the diary: slightly yellowish coloured paper with everyday scenes sketched in black ink. These scenes are overlaid with the portrait of a young woman painted in red, blue, black and pink watercolours.
