Atfer listening, I think it was recorded reel to reel, probably for reasons of assembly / pause etc, and then the soundtrack has been transferred to this folder and shipped to America. I've also heard "Please take care of our daughter, the daughter of the French family must have been in America for the holiday. Not sure. Regardless, it's a neat item simply because in the days before e the cassettes, CDs, home videos and webcams ....... This was a very unique way of sending a holiday greeting to someone. What a joy it must have been for the recipient to hear their voices!
Also, it is cut into LPs and 33rpm. Between the indices of the original reel to reel sound, and this combination of speed and cut, I would personally guess that's from the 60s, but it could be 50 years as well if the person was to 'tech savvy and had some neat toys! [EDIT: A friend translated and reported that the year 1961 was mentioned]
