Marbled spatter in cased glass with red inner - D'Aurys mark

The D'Aurys mark is a Kralik mark usually seen in cameo glass. This one is enamelled onto the surface of a cased glass vase: something that I understand is not unheard of, but which made me doubt myself when buying.

Anyhow, we have an interesting marble spatter which appears "dripped"on, and a brick red lining which we have seen with some other Czech Art Deco pieces.

Actual ID apart, it also has the whoompf of a 31.8cm height - so I am calling it my big Kralik for the mo, but with the caveats that I have explained.
