The Unruly Calf drawn by Winslow Homer 1875

  Karen Sherry is the Curator of American Art at the Portland (Maine) Air Museum.  She used to work at the Brooklyn Museum or Art.  That was where she sorted through hundreds of drawings made by famous artist that would become paintings.  She looked at over 3000 drawings and selected 110 of them for an exhibition.
  When Karen arrived in Portland she was able to attract the exhibition to show us in Maine.  There are Edward Hopper, Homer, Thomas Eakins and many others.
