Scientific Facts on the Beret?

Through an auction I got hold of a number of very old "new" berets; once the stock of a New York hatter, stored for decades on an attic and finally sold to this collector by the hatter's grandchild after a cleaning spree of the old house...

Some of these I sell on to other collectors or donate to museums, but this one here, I am very happy to keep in my collection.

It's a French made Basque beret, only 21.5 cm diameter (8.5") in it's original box. The box proudly displays the US flag and advertises the beret as "American Basque Beret" with a registered US patent. But, more interesting is the back cover, stating all sort of facts about the berets that really make me wonder. I quote the most interesting (or fantastic...) ones:

• When the ancient Roman male wished to become engaged to a girl, he merely snatched off her beret. This symbolized that she was accepted.
• The aboriginal inhabitants of England during battle wore only close-fitting berets and no other apparel whatsoever.
• The Lhardi tribes of Northern Tibet always wear berets made from the hair of departed relatives as a sign of respect.
• Korean gentlemen always wear two berets, one above the other. They take off only the outer one when indoors.

And how do you like this one: Superstitious maidens of Afghanistan sleep with their native beret on so they will not be annoyed by evil spirits that prevent them finding a husband.
