In case you wanted a closeup look at what was shoved into River's head, the Prop Store of London is offering production artwork of that exact creepy beastie.

This printed production used artwork features conceptual designs for the head apparatus seen at the beginning of the film, worn by River (Summer Glau) in the laboratory. The picture has ‘Serenity – Director: Joss Whedon, Production Designer: Barry Chusid’ printed in the corner. Measures 43cm x 28cm (17” x 11”).
