Thanks for the prompt response Peter - I would never have thought of it as a one off. One wonders how it got to Australia.
Vase is a production piece not "one off" to be unique it should have had signed with the number 844 as well.
Holmegaard Glasswork has always participated in many exhibitions through out the World and most of the time, if not always made new design especially to these exhibitions, instead of bringing them home to Denmark again they were sold on the spot, therefore you often can find "one off" in Danish we cal them "unikater" because they often is not "unique" "one of a kind" but found in very limit numbers mostly from 2 to 5 i numbers, very few in on 1, and few between 6-9.
The real unique, in Danish "Unika" on made as 1 item is rare. I also name items that, due to the production metode, as unique "one of a kind" because it come out not quit the same due to the glass making process, as seen in the wet clay "våd lerform" technique.
Do think that Australia, quit early was introduced to glass from Holmegaard Glasswork, probably around 1920 together with "Den Kongelige porcelænsfabrik" (Royal Copenhagen). I am sure you can find Danish glass items close to 100 years old, you just do not notice them, yet :nogos:
In 1978 you had a large exhibition touring in Australia called "150 Years of Danish Glass" it was circulated in Victoria by Caulfield Institute of Technology, Melbourne and organized by Kastrup & Holmegaard Glassworks.
The exhibition contained and showed 333 items and did cover item from 1825 to 1978 with items from production at Fyens Glasswork, Kastrup Glasswork and Holmegaard Glasswork.
When I search the on line shops, and private adds in Australia, I think you do have many, many very fine Holmegaard items, from the almost last 100 years of production, and for my self I have bought several fine items from Australia, also unique glass, in spit of the shipment costs.
Lot of Danish families do have relatives in Australia, and of-cause there also have been a lot of gift exchange over time and what to give dear ones fare away, of-cause the best of the best, so beautiful old Holmegaard items is to be found in Australia.
Good luck with the search.
