This photograph was supposedly taken in Geneva in 1954. I thought it was the Palace of Nations building, but I cannot find any resemblance between it and this building.

Edit:

It could also be San Francisco. The issue is that the caption is vague, listing the "world peace conference in Sweden" and lists the date as 1954. There was no such event, so I was assuming it meant the Geneva conference.

However, I found a newspaper article listing two of the pictured people as attending a "world peace conference" in 1951. I can only assume this is the Treaty of San Francisco.
