Ivo - I would certainly class it as Carnival (albeit probably more recent).
I have seen handles exactly like that on another (unknown) piece. Hhmm, that doesn't help, does it? :roll:
Thinking aloud, it also reminds me of a pattern known as Art Deco that has been found in the form of a little cream jug, bearing a red sticker that reads:
JRIS
and on another gold label above the JRIS,
Made in Germany US Zone.
Any ideas on JRIS?
