A Night At The Opera. Which version?

Hey everyone,
I was kind of "organizing" my LP collection when I had some trouble with my A Night At The Opera LP.

After a little investigation I found it on Discogs:
https://www.discogs.com/it/Queen-A-Night-At-The-Opera/release/7276463

Since the release year is unknown (or at least, not mentioned), does anybody know it? It would be very much appreciated.

Thanks.

I guess you have the German 1976 release.
