Thank you very much, Robert!
It is a phantastic design, isn't it, very modern, and painterly -- as if the colour was applied with the tip of a brush.
I don't know either if every CMS piece from this "range" should carry the etched mark, so I guess it will be impossible to be sure who made it.
My floral bowl does have the "R - Krasno" mark >> Link
Unfortunately the text in the Skrdlovice pattern book is impossible to read for me...
It is just my gut feeling that Skrdlovice pieces from the very early 1950s look different -- different use of colours etc. (but I have only seen a handful, so I may be wrong).
