We’re clearly pretty obsessed with vintage kids’ books, especially ones that have great photography. This one, Be a Frog, a Bird, or a Tree, is so cool. It shows all of these different yoga moves, along with black and white shots of kids, and some beautiful illustrations. The writing is really good and evocative too. Our daughter loves it. And since this is a book that is out-of-print, most people don’t know it, so it makes for a clever birthday gift!
