A biography of Joostens was written by
Georges Marlierin in 1923. He was part of the Dada
Exposition at the National Museum of Modern Art in Paris in 1966. He
won many prizes throughout his career and his work is in several museums throughout the world.
He died in Belgium in 1960.
Many of his drawings and paintings showed up
in New Orleans some years ago. I am not certain why but there is
some speculation that they were sent to a relative or friend during World
War II for safe keeping.
