Denver is trying to raise money to build a museum to house 2000 works from the estate of Clyfford Still. But the terms of the deal are very restrictive. “None of that art can be sold, and some question whether Still’s name will attract a wide audience. Few would question the viability of a Pollock, de Kooning, or Rothko museum, but those artists are much better known. If marketing abstraction to the masses weren’t challenge enough, the artist’s will forbids the display of work by other artists in the museum, so the institution cannot create a varied schedule of temporary exhibitions to lure return visitors.”
