Marcus, I considered that as a possibility.
Frank, The egg shape is the piece I saw, and it bears a very strong resemblance to a Welz decor with the FWK label attached. As far as the ebay seller goes, the use of the term as a decor is incorrect, as I have an image of the label on a completely different decor... Their details are, on many occasions, not the most accurate....
Although the label I am showing appears embossed, the one on the Kralik piece that you linked to appears more like the FWK label and the others I have seen with the same shape and border design.
Thanks, Craig
