I have hundreds of examples of the Wochenspruch der NSDAP on the site. This was a weekly poster with inspiring quotations issued between 1937 and 1944. Before 1940, many were issued by the Gauleitungen, afterwards (mostly) by the Reichspropagandaleitung. My page is the most complete collection available, but it is not complete. New ones surface every now and then.
Just yesterday I found confirmation that the final issue (which I have not seen) was #15/1944. The image is courtesy of MAR Historical.
I, and others, are attempting to find as many of these as we can. Should you have ones not on my site, I’d appreciate hearing about them.
