[Switzerland], Sandoz, 1963 to 1967.
Folio; 12 card portfolios, each containing a section of text (varying from 4 to 8 pages) and a quantity of loose plates (usually 12, almost invariably in colour) printed on stiff card (Series 9 contains 6 double-page plates, each with 24 small illustrations).
Series 6 was issued with 16 plates; numbers 9, 13 and 14 are no longer present. Series 8 ('The Pictorial Representation of Depression' by E. Cunningham Dax, Chairman, Mental Health Authority, Melbourne), lacks the first of its 12 plates. Apart from minor wear to the text in Series 11, and some marks and minor signs or wear to some of the portfolios, this most fascinating series is in excellent condition. [12 items].
