We chose this hard-back book as one of a few to take on a flight with a 3-y-o who LOVES Thomas. We certainly weren't disappointed, and neither was he. The book shows Thomas in several different scenarios (at the beach, in town, at the zoo, etc) and is brightly illustrated with interesting and detailed pictures. For each picture, there are a dozen or so things illustrated round the outside of the main picture with the name of them underneath. This means you can spend some time finding all the individual named things in the main picture as well as looking at the main picture itself. There's lots going on in all the pictures and lots to talk about, make noises for, etc. It's kept his attention for several months and we're pleased that it's an entirely appropriate book for him, with nothing but interesting stuff to see! He will happily look at it on his own or with us. Recommended.
