Incidentally, exactly the same error pops up in the DK book 'The Antiques Roadshow Book of Collectables', along with an illustration of three Gulvvaser, two of which are the Cascade Glass versions, attributed to Holmegaard.

The really frustrating thing is that the book was published Sept 2008, and these same errors have been on the DK collectables identification website since
at least around February/March 2007, when I wrote to them to inform them of the mistakes.
