Thanks to information from Dan Streible, professor of cinema studies at New York University’s Tisch School of the Arts, we became aware of an additional source for our quest for the colors of Caligari (see initial post here).
The Museo del Cine Pablo C. Ducrós Hicken, Buenos Aires under the direction of Paula Felix-Didier holds a sample book of individual tinted and toned frames from “Das Cabinet des Dr. Caligari”.
The restoration by the Friedrich-Wilhelm-Murnau-Stiftung in Wiesbaden is currently under way under the supervision of Anke Wilkening at L’Immagine Ritrovata in Bologna and will have its premiere at the Berlinale Film Festival in February 2014.
