Hi,
William Warmus's catalogue of Vizner's Friedman exhibition is good, but, is a lot of money to pay, for perhaps less than a third of items featured are available to collectors. The section dealing with early work, for the most part Sklo Union pressed, is ok, with a number of pieces illustrated, 11 I think, (no product numbers) but many drawings leave it unclear as to whether they ever arrived in production. Like-wise Skrdlovice production, you are never quite sure if you are looking at a small series piece, unikat(which in CZ is an edition less than 10, limited edition less than 250 examples, small series 1200 copies, or prototypes.
From an academic point of view its ok, for a collector, stick to Millers or Sammler und Trodler, sure, you don't get all the background, but from the id point of view, they are fine. Otherwise, with regard specifically to Vizner, exhibition catalogues rather than monographs render more info, with often many more useful images.
respectfully,
Marcus
