Beautiful ornamental blackletter...

Hey everyone..

Just curious about this beautiful piece of typography.
Be grateful if someone could shed some light over the origins of this work. Typeface, swashes, designer etc.

It is a boxset of classic operas on tape. Published by Readers Digest!!!


Any date on this?

I would imagine it is custom, maybe based in type but heavily amended.


The only thing i can find, is a copyrigt note in the accompanying booklet that says 1978.
