Mac, Great find..... It is Kralik for sure, and the decor is Blue on Gold. The blue is generally a little more pronounced than found on Blue Wave", and the pattern is not a regular up and down "wave".
I have attached an example of "Blue on Gold" (1st), and also "Blue Wave" on Gold (2nd), and also on Orange (3rd).
The 4th image is a "Silberband"

As a side note, the third piece was one of the pieces that helped Al to determine that the "Cardiac" vases, were Kralik product and not Pallme Koenig.
