The Hollywood Film Enterprises have been supplying the shorter length subjects for quite some time ; in fact, during the past year and a half this supply has amounted to several million feet. That sounds like a lot of feet — even of Mickey, but did it satisfy? NO! They demanded more of Mickey, so now to the great joy of the amateur, and those who are not amateurs, they may sit back in their chairs, heave a long contented sigh, and watch Mickey and his pals do their stuff in a full length reel. The Hollywood Film Enterprises, 6060 Sunset Boulevard, Hollywood, can now furnish for your film library the following silly Symphonies, each subject approximately 200 feet, 16 mm.: "The Plow Boy", "The Haunted House", "The Fire Fighters", "Traffic Troubles", "Pioneer Days", "The Barnyard Dance", "Springtime", "The Skeleton Dance", "Midnight in a Toy Shop", "The Merry Dwarfs", "Cannibal Capers", and "Night".

The use of this aperture, which was standard in the days of silent pictures, is now limited for the most part to projection background work. Having no sound track to consider, full use can be made of the larger area of the old aperture to secure the benefits of reduced screen magnification in projecting the background image.
