I was trying a different tack with the photography - not sure if it works - colourless pressed pieces can sometimes give headaches when trying to produce sharp pix.
This particular shape isn't in Mark Hill's book, but he does show a blue jardineire with identical design, and he mentions vases with same pattern - this one is the 8 inch (c. 20 cm.) model - in addition to which there are small candleholders and flat ashtrays - all of which started like apparently around 1967, then onwards. One of the most commonly found Czechoslovakian pressed designs according to Mark Hill.
Fairly heavy for size and with typical bird-bath base.
I think it's one of those abstract designs that could grow on me - bit Henry Moore ish and understated.
