Zhao Mengfu - Twin Pines, Level Distance

This is a twice larger version of the painting by Zhao Mengfu (1254 - 1322) in the current Metropolitan Museum exhibition Anatomy of a Masterpiece: How to Read Chinese Paintings (see a New York Times review and slideshow). I have seen it also called Twin Pines Against A Flat Vista. It seems that there are a couple more know versions in US museums (I read an article about it a while ago, and will post a link when I succeed in locating it). The inscriptions on this one are by Tang Yin and Mo Shilong.
