Jackson Pollock was continually involved in "process and experimentation." This is reflected in a small but significant retrospective of his work over a 20 year period, presently on view at MOMA. Pollock was instrumental in the creation of the Abstract Expressionist movement, the first American art movement that then became prominent in Europe as well.
My photo does not do justice to the depth that this painting projects.
If you get a chance, go to MOMA and see for yourself. You may agree or disagree, but I think you'll find the exhibit worthwhile.
On your way, you'll also catch the huge stainless steel sculpture now on the center island of Park Avenue, around 53rd St. Manhattan is quite a backdrop for sculpture!
