1973, Architecture for the new world.The world of Harry Seidler by Peter Blake.
 
This is a first edition hard-cover with a dust-wrapper published by Horwitz. The many photographs are by one of Australia's greatest photographers, Max Dupain. The book also has many diagrams showing Seidler's extraordinary skills.
 
The dust-wrapper has some minimal soiling and a few small chips other than a small split on the spine (see photo). The book itself is near fine.
