In A Holiday, Edward Henry Potthast used a luminous palette to capture the sun-drenched sensations of a day at the seashore. Light gleams on the bathing dresses of the group of girls in the foreground, while their reflections sparkle on the water swirling at their feet. Beyond the sandbar, waves break into foaming white crests, and deep water darkens into rich shades of blue under a cloudless, aqua sky.
