The Discovery of the Americas: From Prehistory Through the Age of Columbus - Betsy Maestro, Giulio Maestro

This is a remarkably broad topic for a picture book to tackle, but I think they've done a nice job. I like that the books starts with prehistory and that Columbus doesn't pop up until well over half-way through the narrative. This book serves as a nice overview/preview of the various expeditions to the Americas. I wouldn't use this book alone to teach/discuss the Age of Exploration/early American history, but still it's a nice supplement.
