Commercial copying
Any form of commerical copying of Gerdine Duijsens’ artwork will have (legal) consequences.
See the court ruling (link) of Gerdine Duijsens vs. Theo Broeren.
In short:
The verdict of August 15th 2010, at the Dutch Court of Den Bosch, reads:
"Theo Broeren violated he copyright on three paintings of Gerdine Duijsens. The court obliges Broeren to hand over the artworks to Gerdine Duijsens, to be destroyed."
