Short description: An etching after Albrecht Dürer’s “Preying Hands” by Fritz Neumann. Even if the motif and style doesn’t match, the signature does.

Notes: No blind stamp visible.

Short Description: Sailing boats in a harbour / near a shore

Notes: Another maritime subject by Fritz Neumann, on the back is a sticker reading “Echt Aquarell” (Original aquarelle). But this is clearly a colourised print, since there is a platemark.

Description: Another work by our Fritz Neumann, look at the signature and the stamp mark on the third picture.

Notes: Taken from eBay Kleinanzeigen

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

A signature of Fitz Neumann (1881 - 1919), taken from findartinfo.com . His subjects are mostly Cossacks, he was a painter.
