Flotsam is an silent picture book where a boy finds a camera on the beach. As he develops the fantastical underwater photos, he stops at one of another child holding a photo on another beach. The photo in the photo is of a child holding a photo of another child and so on through a lovely Droste effect until we arrive at a scene reminiscent of San Francisco’s Cliff House in its heyday. The boy then takes a selfie holding this recursive image and hurls the camera into the ocean. Full of color, sans words, this is Wiesner’s Caldecott-winning best.
