Detail, Southern Bell Telephone Company Building, Atlanta, GA

Cornerstone indicating completion in a fateful year.
From a page I found called “Atlanta Telephone History”:
In 1948, the building was expanded to 14 floors. New Long Distance operator positions were installed on the 7th floor. The expansion opened in October of 1949 with an Open House for the press and the public.
