There's no date of publication, but it is heavily "foxed" ... but there is a clue on the back cover ...
That must date it well back into the past. The Jurassic Epoch maybe.
But what about the actual "learning" bit ... I didn't think much of their pronunciation guide ... the "r" section doesn't make any sense.
The "r" in Arrow" isn't trilled at all. We don't say "arrrrrrow".
I've also got another slim volume ... " Learn Norwegian in a week"
And I don't believe that either.
Maybe all Finns learn it in a week .. those long, dark winter nights !
But more of this later .... music time looms ....
