Set of 8 wooden geometric models

Set of 8 wooden geometric models, Belgium first half 20th century. They were issued by Instituteur J.B. Romain, based in the green, lush hills of Spa. These sculptural beauties were used in schools & academies to sharpen the vision and skills of students and artists. Although they happily survived bad weather and several moving operations, they witness of some coming-of-age symptoms. There are some dotted areas, and some minor chips in them pointy ones. However, nothing too disturbing!
