I could look at the pictures for hours (in fact, I have). I have a similar book, 100 Nouveau Créateurs De Mode, that I picked up in Paris at The Louvre when I was there the last time on my study tour in college. It's obviously in French which definitely helps me keep my years of French class useful.
I would highly recommend both of these. They are FULL of runway pictures, photo shoot pictures, and sketches from each designer. They also have information about each designer. So interesting!
