These water puppets are REAL! They are designed and hand made by the artist, Nguyen Quoc Hung, who is making water puppets for the Thang Long Water Puppet Theatre in Hanoi. All the water puppets in this group are made with the same size with the real performing puppets in the theatre. We also have some pictures, action shots, of the same characters in the water puppets shows. All the pictures are from the Thang Long Water Puppet Theatre.
