I'm going to be critical and this might disappoint some people here but...to the best of my film knowledge, that French video is not from that era, it was just filmed to look that way. The "silent era" was just that, silent. Any music that accompanied the films was actually piped in by a pianist playing the music live. And ANY dialogue would have subtitles, they didn't pick and choose. And since the music was seemingly part of the film itself, that's a dead giveaway that it's not from the 1910s or 1920s. It wasn't until The Jazz Singer, released in 1927, that movies started to include sound and/or music and even then it wasn't commonly used for a few more years after that. Also, Steamboat Willie was one of the very first cartoons with sound and/or music, and that came out in 1928 which was 3 years after the supposed last year of that compilation. And I'm almost positive that gloryholes was not a thing back then. But I actually did enjoy the cartoon and its creativeness. But again, the video game Cuphead showed that anyone can recreate the look of 1920s/1930s cartoons. If anyone can prove this wrong, by all means, go ahead. I just don't see how it's possible that a collection of French pornos was able to be preserved in surprisingly high quality for what would have been the time, but also landed in the hands of someone who was able to then upload it onto the internet in 2019.
