I started perusing ebay just to see what was out there, and came across this Danish course. It says Linguaphone, but also "extracts from teach yourself Danish" written on that book, which I thought was a wholly unrelated course.

The same thing is happening in this Cantonese course:

Anyone know what that is all about?
Anyway, from the dust-jacket of my older Spanish course (50-lessons on records), I copied the following:
Full courses published by Linguaphone so far are as follows:

The only example from the latter list I found on ebay was this Welsh course. Now, it is on cassette, and thus may be different from the original course, but I have a sneaking suspicion that there was not a huge push for an updated Welsh course in the mid-1970's, so I think maybe it is safe to assume this course was the same whether on record or cassette? If so, it looks like it only had 25 lessons. Though, I am a bit confused since my google-fu told me "gwersi" means "lessons" and this has three tapes saying gwersi 1-15, 10-14, and 20-25. So one is left to wonder about gwersi 15-19!

Then there are the courses missing the handy carrying case, like this Russian one. It just is a shame it is impossible to tell if this actually includes all the parts!

On the topic of the complete courses, does anyone have a complete list of the later 30-lesson courses? Sadly, though my 30-lesson Spanish had the dust jacket intact, it didn't offer any insights into that generation. Also, does anyone know if the 30-Lesson courses are the same across all languages in the same way the 50-lesson ones were? Or are they all unique/distinct?
Anyway, though I am only a bit into my Spanish studies, I find myself quite charmed by these older Linguaphone courses and will probably look to study any future languages with them as the base as well.
