The book ‘Blumen Blätter Zweige’ (published in 1967), roughly translating to ‘Flowers, Foliage, Branches”, by Ingeborg Wundermann features some West German vases as examples of containers which could be used for flower arranging. The vases are perhaps by Ruscha or Otto Keramik.
  
The book also features some very stylish photos, as well as some rather strange arrangements – tinned food and kitchen utensils in a flower arrangement?
