"© Distrib. Por Norma" The signature/credit appears to be a single name "Lalia Albiac". Lord Jim appeared in Delta 24-26 and 31 (1982).
"© Distrib. Por Norma" Signature appears as if it is intended to be two separate names.
"© Controlled by NORMA" S.O.S seems to be a likely source for this story, but that might not be accurate - it could be another story of the same name.
