Frog Song by Brenda Z. Guiberson, illustrated by Gennardy Spirin is beautifully done in a classic style. There is a paragraph of scientific facts about a specific frog and the art brings this book up to another level.
The art in done in impressive tempera, watercolor, and pencil paintings with remarkable detail and an ethereal artistry. This informational text will be used in classrooms and homes. It would be a great introduction for older and middle school students, as well as a good read aloud for 3rd to 5th graders.
