Black-white drawing is not about learning reading, but observing relationships of objects in the drawing. It is baby's best first book, guiding and growing up with them. A banana, a dog, the Sun, etc. all have high contrast between black background and white drawing. It is not a book of no words, but with voice of Chinese and English which attracts babies' attention and inspire their imagination.
