I'd like to send this letter to the Prussian Consulate in Siam by aeromail. Am I too late for the 4:30 auto-gyro?*

This image of an autogiro, photographed by the Aero Service Corporation around 1935, was used by the Chamber of Commerce of the United States for publication in Nation’s Business. The Chamber, a private lobbying group representing American business interests, used this monthly publication to inform the business community about commercial trends and to solidify political support around key positions on government policies regarding business and economic life.
