Denmark   Danish National Bank guard’s visor cap The Danish National Bank, “Nationalbanken” is the place they print the money, so not many people are familiar with this cap. My ex-father-in-law was a director of the bank from 1957-79, which is how I got to know it. It’s basically an air force officer’s cap with a different wreath. This turned up at a flea market along with several other interesting and unusual caps.
