and the answer is.......... that it's on the Skol Union data base CD - so Czechoslovakian, and the piece I'd remembered seeing is the same i.e. a bookend, although shown only in black and white of course. For reference it is: Libochovice Glass Export before 1958 (fourth catalogue down) - item No. 2265 showing at the top of page 53. Size is given as 205mm (8"). Very attractive to have a pair in u. - although I doubt that words like iridescence and depression are correct when used in relation to these figures.
