These illustrations are for a series of children's books in the spirit of "FIND WALDO" or
"I SPY". The main theme of the book is the structure of the city, in particular, the urban infrastructure. The child is explained the basic principles of the station's arrangement: what kind of people work there, how trains function, etc. For better understanding of the information, the reader is invited to perform assignments focussed mainly on testing memory, awareness and attentiveness — finding and counting the objects listed for each puzzle picture.
