pple Tree, Pointillist Version (1908–1909) is a significant early painting by Dutch artist Piet Mondrian, showing his move from traditional landscapes towards abstraction through his experimentation with Pointillism and Theosophy, featuring dark, swirling branches and a vibrant blue background to convey nature's spiritual energy before his famous geometric style. It's an important transitional piece in his evolution, now housed at the Dallas Museum of Art.
