Topic: Heavy yellow vase with white stripes

[rdorrer]

Hi, here another unresolved piece of my starting collection:
It stands 18 cm high, weight is 2.3 kg, top is 8.5 cm diameter, stand is plain and 7 cm diameter.
It has a written signature, with 3 words. second and third is "Studio Crystal", and the first is hard to read, see last picture. It might be jax, but I may be mistaken.
Thanks in advance or any help.
