Hello again

I have an LP made by A.B.C.    (J. Naftali Records). Of singer Albert Ortiz (The Yiddish Golden Voice of)
I need to know if there's any chance of copyright issues.

Might there be a list of labels that are definitely not copyrighted anymore.
Of course, there's are the artists that might still be alive and copyrighted.

I don't intend to make copies or sell them, just to put it on a free website.

Regards,
Ben
