Superman, Italian edition publ. Albo Mondadori (?) - is it in the db?

[Michael R. Wagner]

I'm trying to find this series in the database and am beginning to think it's not in there.  It's an italian edition.  According to the Grand Comics Database, it ran for 77 issues between 1967-1970 w/ issue numbers 575-651.  I have some issues and would like to upload covers, storylines, etc.  Has anyone heard of this series, or perhaps knows within which Superman title it's hiding?
