Published in 1967 \'an enquiry into the development of a symbol\'. Prefaced by letters from the late Dr. C. G. Jung and Frau Aniela Jaffe to the author with regards to his manuscript. No dust jacket. Boards in very good condition. Internally mostly clean and in good order - just some very slight staining on the top edge of the front pastedown and front free endpaper. Also some light foxing on the back endpapers and last page, and on the cut edges of the text block.
