David M Checkley Watercolor Sketches:

My father, Dave Checkley, never went anywhere without his paints and sketching supplies. Everywhere he traveled he not only took photographs but made small thumbnail color sketches like the ones shown in these collections. Some of the sketches would later provide him notes for making full size paintings al fresco or later in his studio. Invariably, they are fresh and colorful and full of light -- and they evoke a vibrant, if tiny, sense of place.
