A book of very simple models to make yourself a multitude of small drawings in connection with nature. Each spread among 45 has 20 different models (and single) each theme like "tree" or "leaves" or "dandelion". 900 models at all so to illustrate a newspaper art, drawings or text easily with a simple pencil or brush calligraphy. Very useful and practical because each page leaves a little room to add their own creations or other models.
