That there should still be, in 2009, degrees of neglect in an artistic movement as heavily studied as Abstract Expressionism may be a surprise. But the artist Jack Tworkov certainly belongs in that category. Born in Poland, in 1900, the artist emigrated to New York at the age of 13 and spent most of his life pursuing a wide range of abstract styles. He hasn't gone totally unnoticed. His "Watergame," shown here, sold for an auction high of $396,800 in 2005 at Christie's.
