'There’s a Paul Klee sketch hanging in the San Francisco Museum of Modern Art titled A Guardian Angel Serves a Small Breakfast. The figure hovers just above the ground, its wings spread. It holds a tray upon which breakfast items, including a kettle, are intertwined with one another, a tangle of gentle lines. Liquid pours from the kettle’s spout, even though it isn’t tilted. Emerging from the angel’s chest is a small love heart in red watercolour. There are many lessons to take from this sketch, one being that it’s good to serve someone a small breakfast.' (Introduction)
