 For many years this film only existed in murky 9.5mm dupes on the  black market. In March 1973, at a screening of this film at George  Eastman House, archivist James Card said that Henri Langlois (qv)  and his staff at the Cinematheque Francais discovered a copy of it  in 1968 among other miscellaneous cans of film marked "linconnu"  (films "unknown" due to missing titles, etc.).
