The bowl is an example of Loetz Ausführung 218. Ausf 218 is a solid ground with a connecting pad of contrasting color between two parts. Most commonly found with a rim of the same color as the pad. The candlesticks are also, in my opinion an example of Ausf 218, without the applied rim color, but with the contrasting connecting pad and solid ground.
They are not a Powolny design. Powolny designed far fewer pieces for Loetz than he is credited with on the internet, and these would not fall in the category of product he did design. He was not involved in the design of Ausf 218.
The internet myth that he was responsible for Tango, and a large number of other decors for example, is just that..... an internet myth.....
Nice set.....
Any marks of any kind inside the bases?
