Bloomberg has a few sales from Maastricht:

The 1982 Basquiat painting, showing a black figure and titled “Busted Atlas 2,” fetched $2.4 million. It was sold at the booth of the New York gallery Van de Weghe Fine Art to a German collector, said director Christophe van de Weghe.“Interest in Basquiat has increased because of the retrospective on the artist that’s going to be held at the Fondation Beyeler in Basel in the summer,” Van de Weghe said in an interview. The gallery had also sold two table mobiles by Alexander Calder for $530,000 and 240,000 euros, ($330,170) respectively.
