Hi Jon, like the neat finish of your white lamp. I have a large collection of Murano lamps(mostly Archimede Seguso or SvDA). I bought them as they are very reasonable in price, most of them around 50-70 Aus $$$ each. They occasionally come with a label but mostly without.
It's an excellent way to get an example of a piece of glass that would cost hundreds + if it is a vase, yet you can buy the lamp for 1/5th of the price. I also like to have them around the house.
I'm hoping that table lamps don't come back into fashion until I have filled my requirements.
