From CFS website: "The Chicago Film Society sells a 16mm projector alignment test film developed by L’Abominable in France. The test film was produced with the dedicated tools that were deposited with L’Abominable by the French Commission Supérieure Technique de l’Image et du Son, who was in charge of producing such films in the past.
The film was made under the banner of filmprojection21.org, and is sold in 10 foot lengths."
