Just got this one in, it's very pretty! In contrast with the more freeflowing pieces I've seen labeled and described as Czech, this one looks really geometrical. It's circular, as wide at the top as at the bottom (though some pictures taken from above suggest otherwise). It has four large flat oval lenses on the sides, equally spaced. The rim and base are flat. Couldn't find anything similar online so far, or in Mark Hill's book (though the oval lenses seem to come back in several designs). It's fairly heavy for its size.
Measurements are 9 cm high, 11 cm wide. 7.5 cm wide at the base and 6.5 cm wide at the rim (with the opening being 4 cm wide).
On the photographs it looks quite pink, but sometimes it looks more blueish depending on what light is on it. I'm to inexperienced to tell whether that means there is a special ingredient involved. Tried the UV light on it, but it didn't light up or anything like that.
The label is the (general?) Bohemia Glass, made in Czechoslovakia, but in a black background with gold lettering (unfortunately that particular combination was not mentioned in Mark Hill's book, nor on the czech label collection online).
I'm sure experienced sklo and/or czech glass lovers on this forum can tell me more about the factory, the designer and/or the time period the label would indicate.
