Max,
this shape (no 2) appears here often, in different sizes and different colours.
Only the vase dispayed at attached picture is for the moment fully attributed Skrdlovice 5988/30 - Jan Beranek. In fact it is only longer shape originaly designed by Jan Kotik. This vase had been fabricated for many years, also in Beranek's privatised factory last year.
The simmilarity does not mean attribution, I am seeking confirmation for other shapes, but it is question rather for weeks than for days.
