I was recently in an antique shop and found a small film box (with a big price tag...) It was printed in purple and orange on white and read "Official Souvenir Motion Picture Film, 1934 Century of Progress Exposition; Manufactured by Kaufmann & Fabry, Official Photographers, Chicago. 50 feet, 8mm, Safety Film." And inside was the film as described. This is a VERY early 8mm home-movie short subject release; predating Castle Films' Hindenburg newsreel (the first "hit" home-movie short) by several years. In fact, I believe 8mm itself had only been on the market a year and a half or so then. (I assume they had 16mm prints too.) So K & F were apparently also pioneers in the home-movie field too!
