This is London by Miroslav Savsek was the best book I discovered last year when visiting the library for books on the city for my four year old before our visit.
The book was first published in 1958 and, despite the statistics being dated (updates are provided at the back of the reprinted books), the illustrations and story were fascinating to my son and conveyed a love of the city better than more modern books that contained photos and an array of information that wasn't in a story format.
As most of the landmarks described have remained, the book familiarised him with many places that he was excited and enthusiastic to see during our stay.
Only recently did I discover this is one of a series of eighteen, including Paris, which I wish I had seen before our trip, and one of Australia.
