I am loving this vase

my feeling is Czech and probably ZBS
there is a similar beast in Mark Hill's Hi / Lo book page 48 by Miloslav Klinger
Do I remember reading somewhere this colour combo is specific to ZBS? can't find a thread atm
very tactile, huge dimples with a slight twist. Ground and polished base
just lovely.
can anyone confirm or put forward another ID please as a bit out my comfort zone
many thanks
Mel
