Beautiful frame tray puzzle from Norway, made by the Asmund S. Laerdal company.
The Asmund S. Laerdal company - or more properly Åsmund S. Lærdal, was founded by, you guessed it, Åsmund S. Lærdal, a noted Norwegian physician. According to his Wikipedia page, he founded the publishing house in 1940. Surprisingly his major contribution to the world was not this puzzle, but rather CPR. In fact, he was one of the developers of Annie, the CPR training mannequin.
