The "Century of Progress" International Exposition (Worlds Fair) was held
to commemorate the 100th anniversary of the incorporation of the city of Chicago.
Its theme attempted to demonstrate to an international audience the nature and
significance of scientific discoveries, the methods of achieving them, and the
changes which their application has wrought in industry and in living conditions.
This was done through exhibits that appealed to the public, often with miniaturized
or replicated processes.
The fair was held on 427 acres (much of it landfill) on Lake Michigan,
immediately south of Chicago's downtown area, from 12th Street to 39th Street (now
Pershing Road). Today, Meigs Field and McCormick Place occupy this site. The
"Century of Progress" officially opened on May 27, 1933 and closed on November 12th
of that year. Although originally planned for the 1933 season only, it was
extended for another year, reopening on May 26, 1934, and closing on October 31,
1934. This extension was due to the fair's public popularity, but mainly as an
effort to earn sufficient income to retire its debts.
To commemorate this Fair, this letter was sent round-the-world from the
"Century of Progress."
