This image is a colorized, and closer in view of the Wilson Memorial Plaque as it looked in front of the Palais des Nations.
The description states:
Genéve – Palais des Nations et Plaque commémorative Président Wilson
–A person standing at this point would have their back immediately to Lake Geneva. As noted earlier, this building was replaced with a new United Nations building and is now the Wilson Hotel.
This card likely dates from the 1920s.
