Chang performs Asrah in front of a beautiful dragon curtain. Notice the hanging trunk (actually two nested trunks) on the right top corner of the photo where the girl will reappear after vanishing. Chang performed Asrah after performing Aga (the usual levitation without the vanish at the end). This he usually did in the context of a magical sketch. See The Enchanted Princess. In his early days as Li-Ho-Chang this illusion appears in his printed programs as "Astrala".
