This book documents Baumann's visits to Upper Mustang in the summer of 1992 and February 1993. He documents the trek and Lo Monthang including the sights, the people, Buddhist practices, the Tiji Festival, and meeting the King. He also trekked to the souce of Kali Gandaki and climbed Kang Gongaria (6180m).
This is a very good photographic account of Upper Mustang. You may not be able to read the detailed German text, but the photos speak for themselves.
