Short description: A tile with a print called “Am Wind” made by Rosenthal
Notes: Found on lauritz.com . There are many other examples available on the net (Google Image Search ). According to this page , the mark shown had been used by Rosenthal between 1939 and 1956. Another hint from this page is confirming this by the used style of the underline.
Update: Rosenthal answered my inquiry
