This book is one of the main witnesses of Hof's love for London. One hundred and eighty drawings can be found as a result of a many years of a skilled work during which Hof managed to create his own technique. He first drew on a film material and then rubbed the Indian ink with an utensil he had made himself : this produced subtle effects and nuances. He used to do enlargments of this photograph transparent sheet, and modified what he thought necessary. Hundreds of proofs were found in this place after his death.
It is easy to see his fascination for urban art and the knowledge he got from his studies in Prague Polytechnical School. The exactitude and closeness to the models are proofs his architectual habilities : The Crypt St Stephens, Westminster Abbey, Edwardian Whitehal or Victoria Station. We can observe his ability to give volume to paper and to buildings, as well as depth to the streets, and his capacity to emerge the secularity of the sculpted stones. But this highly poetical work would be uncomplete did it not represent its inhabitants : the beggars, the violin players, the busy workers and the confident and careless children.
