A visit to Switzerland in 1946 involved touring a number of venues. On a "G.I." tour my Dad collected a number of post cards. "Le Palais des Nations" was included in his collection.
Geneva (Switzerland) it reads on the back. Mont-Blanc is pictured above the horizon. An impressive site it must have been coming from Winchester, KY with a population of 8,000 souls.
The Bureau of International Travail is pictured next. There must have been lots of folks visiting this place around the League of Nations. International travel would certainly be involved, but it looks like "Le Palais des Nations" takes up a little more space.
