David, this is an interesting post. For the moment I am not sure. The closet similarity I see is to " the basket for sale by Wayne as 'Pizzicato," which I am sure is part of that range. This looks so similar yet just in a different colourway. Without concrete proof it hints to me Machovská. But of course, as you know, we know so little about her career. It is an interesting post and I do not have a definite answer.... (Also Karel Zemek designed some hot worked glass and worked at Mstisov, so I understand. Some of his designs look very Skrdlovice, Karlovarske Sklo too......) Attributions test us all at times..... maybe Jindrich can help us .....
