Hello, everyone here has been most informative. I have done my best to verify the existence of the poster/print I have. The item is printed, I looked at it through a loop and could see the CMYK dot pattern. It measures - printed area 30cm x 41cm with the total paper area 34cm x 45cm. The paper has a noticable warp and weave. The image is that of "Bewahrte Truppenfuhrer des Heers - Generaloberst Guderian". On the bottom left is printed "M/1257" and has a copyright date of 1943 in Berlin.
I found that Willrich moved to Berlin in 1943. I am familiar with his postcards but have NEVER seen a poster of any personality. Please help me determine if this is a 3rd Riech item or a marketing gimmick for "collectors". Thanks
