Here’s a nice book from one of Li Zi Ming’s students. (Li Zi Ming is one of the most famous instructors of the 20th century a student of Liang Zhen Pu.)
Besides being in full color, this edition has nice open pictures, some clear historical photos, some sections on principles of Bagua from a modern standpoint, applications mostly centered on unusual Bagua throws, and of course the Dragon Shaped Palm. Over 100 pages, all in color.
