NEW YORK TIMES, Oct. 3, 1990  

* German reunification - Germany

The first of this notable event we have offered in this iconic newspaper.
The banner headline announces: "TWO GERMANY UNITED AFTER 45 YEARS WITH JUBILATION AND A VOW OF PEACE" with various related subheads. Also a photo of the German flag unfurled in front of the Reichstag building in Berlin.
The complete first section with pages 1-34, nice condition.
