I am sorry that the link for "art in town", with deadline 6 of may does not work. You can copy paste, and you will find the page anyway.
You can winn 50.000 kr and there will be an international jury of well known famous nordic artists picking out works, They do not give any names.
I am sure that a company of this size, have lots of money and contacts, no need to worry.
Diners Club own the right to use pictures of the art work on their web page, it might be an advantage for artists to get art out through other chanells.... Remember Diners Club advertice credit cards...... And I will say no more.
They take no resposibility if the works if it is stolen ore destroyed, but I think it is normal practice.
Good luck
