A Rothko, a Twombly and a Surrealist box with a Medici princess by Joseph Cornell are estimated to sell for $145 million.

Christie’s will auction works by Rothko, Twombly, and Cornell from the collection of the late arts patron Agnes Gund this May.

Long before museums made a point of broadening their collections, Gund was buying work by women and artists of color and urging institutions to do the same.

Here's what we're reading this morning, folks.

The sale of works by Rothko, Twombly and Joseph Cornell posthumously continues her legacy of charitable giving.
