Adolf Feller's 54,000-Postcard Collection is a hot item in the news, worldwide.
Just search the name of the new book about this collection:
"The World in Pocket-size Format: the Adolf Feller Postcard Collection"
You will be able to read one article after another, all of them from 'news' organizations that slavishly copied from one another.
But you will need to read more than one article after another to find out that the archive is somewhere in the bowels of the Swiss Federal Institute of Technology.
The book, BTW, can be purchased at:
