Wordless picture book in black and white. I like the art, and since it's wordless obviously this is a big deal. The book is happen a girl walking around in a city looking at windows and just imagine what could happen on the other side, in the room behind the window. Funny, imaginative, original and beautiful. The pdf format wasn't the best way to read it because of the way the page are frame but in a physical book I really thing the experience would be even better. Worth the time!
