A Dunhuang Buddhist banner with a Bodhisattva image from the late Tang period was acquired by the Jinmotang Calligraphy Research Foundation. The banner is well preserved, though lacks a title, the printed Bodhisattva image is outlined clearly in yellow. Fortunately, Zhang Daqian’s inscription, which was mounted as a small scroll, mentioned that there were two other parts of the banner collected respectively in the"Ancient Capital" and in his own collection. By examining related images and materials, the author has come to believe that these are three parts separated from a longer original long banner. He has therefore begun locating Dunhuang Buddhist banners and related line drawings in both domestic and foreign museums and institutions,hoping to draw more attention to this type of artifact.
