I got this a bit apprehensively to be honest as it is a little pricey but I'm really happy with it.
Great fold out book that is great fun to read and to look at the pictures (I realise that makes me sound very childish and possibly retarded). Im 26 years old with no kids or anything, but this would be great for anyone of any age to enjoy. I mean I wont be throwing this up on the wall as it is intended to but I will happily flick through it. I can see a kid really loving this thing though as it is interesting having a book that can instantly transform into an informative loooong poster.
The artwork wont blow you away and the information isnt going to get you a scholarship at Cambridge but its the brief simplicity that makes this a book aimed at both laymans and children alike.
The only problem with the item (and this isnt really a problem to be honest), is that the pages are double sided which is fine for me as I wont be hanging this on a wall, but if you want both the picture side and the extra info side hung as a poster you cant (or you would have to buy 2). This really isnt a deal breaker though but just thought Id mention it.
Anyway this is a good picture book for all ages!
