The 20th anniversary of the ballet school (1971) was celebrated with an exhibition and numerous performances at the International Cultural Centre in Antwerp. The icing on the cake was the book ‘20 jaar Dansen – Het Stedelijk Instituut voor Ballet’ (20 Years of Dance - The Municipal Institute for Ballet). Over the years, the school grew into an institution with 126 pupils, 12 dance teachers, 7 music accompanists and 20 teachers for general subjects.
