Leçons de choses by Deyrolle and Louis Albert de Brogliehas been the source of much inspiration as of late. It is a marvelous book that we picked up while vacationing in Paris. The colors in this book are amazing! The illustrations are simple and beautiful. It's a lot like a visual dictionary. There are chapters on human anatomy, plants, animals, industry, and domestic life.
Plus, it has a vintage grammar school feel to it that I find irresistible. It was a great find, I feel lucky to have stumbled upon it!
