Esperanto Promotional Record from 1940's or early 1950's

I have started recording some of the 78 RPM records from the Connor collection. Here is a nice promotional piece (3:30 minutes) for their book, correspondence course, and the language in general. They also have recordings of some radio broadcasts, some music, and their correspondence course.
