Two books written by the pioneer of ‘naturism’ HANS SUREN (1885 - 1972). The first is the hardback copy of: ‘Gymnastik fur Heim, Beruf und Sport’ (Gymnastics for Home, Work and Sport’) (Stuttgart: Dieck and Co.), 1929. 256pp. 8vo. A copiously illustrated book depicting men and women exercising and in risqué poses. Accompanied by a 34pp. pamphlet listing additional exercises, and a collection of five illustrated accordion pamphlets, 12pp., offering exercises for specific parts of the body. All of the pamphlets are held within the back of the book; WITH another of Suren’s books: ‘Atemgymnastik’ (‘Breathing Exercises’) (Stuttgart: Dieck and Co.), 1929. 164pp. 8vo., hardback copy. Like the previous book, this is very illustrated. Both books display some spotting throughout and wear to the cover, else very good.
