I bought this book for my 1.5 yr. old son, and also for myself as I have always liked Harper's illustrations. The book itself is very strongly bound and the pages cardboard so suitable for kids.
The book starts off well; A is for Ape, B is for Bird... etc. but then you get to 'N is for Nest', as far as I know a nest is not an animal? Nor is 'U for Underwater' or 'W for Web', but I can excuse the X page as I cant think off-hand an animal starting with X. My point is this is not easy to explain to a child why they are all animals apart from 4 spreads, I still suspect my son thinks 'underwater' is an animal, so that is my first criticism.
My second is the reproduction quality. A couple of the images are reproduced very poorly and look like blurry low quality scans than images fit for print. This may not bother most of you (or you kids) as the illustrations are great but being a graphic designer it does disappoint me.
Having said that I am still happy I bought it and my kid loves it.
