In One Afternoon by Yumi Heo, Minho and his mom go into town to run a number of errands. While they are out, they are swept up in the noise and bustle of the city. At the laundromat, they watch the clothes thump and spin in the machines. At the ice cream shop, the shake machine fills up cups with motorized, metallic whirring. The cats and dogs in the pet store bark and meow, while birds twirp. After experiencing the sights and sounds of these and many more places, it is time for Minho and his mom to return home for some peace and quiet. Minho lies down on the couch to rest, but finds that a leaky faucet will not allow him the quietness that he expected to find at home.
One Afternoon focuses more heavily upon pictures than on text. While sentences are provided on each page to identify the location to which Minho and his mother have traveled, there is not much description or detail provided by the text beyond that point. Characterization is not much of a consideration here, since the book is mainly a visual feast of sights and sounds. The sounds of the various objects, people, and animals in the city are represented in the illustrations through large painted letters. Many of the sound words represented in the drawings are graphically representative of the objects they portray. For example, the “vroom” of cars is depicted with letters that look as though they have been run over by tire treads. In addition, the size and boldness of the onomatopoeic words correlate with the loudness of the sounds they represent. The “wufs” of the dogs are painted in large, thick black letters, perhaps to denote their loudness and force. The “meows” of the cats are medium-sized, and the “tweetles” of birds are printed in tiny letters, as if to match their smaller voices.
The artwork for this book was drawn in pencil and filled in with oil paint. A collage technique is also used to provide texture and visual appeal to the paintings. The illustrations are full of a variety of colors, objects, and textures, all dancing around the page in a haphazard organization that does much to evoke the sense of hustle and bustle found in urban areas. The illustrations typically consist of a plain colored background, with objects spread around the page. With so much going on in the foreground in terms of noise and activity, detailed background textures would be overwhelming and distract from the story. In addition, the figures and objects found in the paintings can be described as highly stylized. The people have large ovular heads that are disproportionate to the rest of the body. Thin arms and legs sprout of barrel-like torsos, while objects such as ice cream cones and dogs are drawn very loosely and freely, without strict attention to symmetry and realism. This style of art does a good job of reflecting the modern feel of the city shown in the book.
