I've seen one of these on Ebay attributed to Rosice, but with no evidence, it certainly has similarities to pieces in the pre1958 catalogue. A lot of earlier pieces I've seen by them are dated to 1957 but I'm sure many of the designs date to the 1930's, but there are no catalogues to back this up. This article on carnivalglassworldwide is interesting.
