Detail of 'Bonnie with John' under painting

Part of an underpainting done with burnt umber and ultramarine blue on a wooden panel of a friend who was pregnant at the time. She is holding ultra sound images of her yet to be born son John. The basic figure was laid out using a sight size method with proportional dividers but the images of John were transferred directly.
