Thank you for the update. To me, this is truly one of the most important parts of LMW. Not to diminish people that want to see a cartoon or advertisement from their childhood, but films are a part of our cultural heritage, and the loss of a majority of films from the silent era leaves a large hole in our appreciation of the era.
I consider it an absolute win even if it likely wasn't at the top of anyone's list. No household actors and not based off a hugely notable story. It seems the biggest claim to fame for the film was being part of the Carl Laemmle-endorsed “The Laemmle Nine” nine films. The association with Laemmle is enough to add notability, being the founder and head of Universal.
That footage is also absolutely fantastic. Not sure if the announcement was made after it was digitized, or they simply worked fast. But such little decay is nothing short of a miracle for a film in a basement.
