This is an authentic period hand-signed (in ink) photo/post card by Gauleiter (regional leader) Julius Streicher.
The back features a vintage appearance postcard from Photo-Hoffmann, the studio famously associated with Heinrich Hoffmann, who served as Hitler's official photographer. The text further provides the address of Hoffmann's photographic studio in Munich (Friedrichstraße 34).
The postcard further provides a German legal notice (Nachdruck verboten) which means reproduction is prohibited, indicating the image on the front was copyrighted.
"Echte Fotografie" translates to "Real Photography" confirming the image on the front is a real photo post card (RPPC), meaning the image was printed directly onto photographic paper rather than being a mass-produced lithograph.
About Hoffmann:
Heinrich Hoffmann (1885–1957) played a central role in Nazi propaganda. His studio produced millions of postcards, books, and portraits of Nazi leadership. After WW2, he was classified as a "main offender" (Hauptschuldiger) by a denazification court, resulting in a prison sentence and the seizure of much of his photographic archive, which is now largely held by the Bayerische Staatsbibliothek (Bavarian State Library).
About Streicher:
Julius Sebastian Streicher (12 February 1885 – 16 October 1946) was a member
of the Nazi Party, the Gauleiter (regional leader) of Franconia and a member of
the Reichstag, the national legislature. He was the founder and publisher of the
virulently antisemitic newspaper Der Stürmer, which became a central element
of the Nazi propaganda machine. The publishing firm was financially very
successful and made Streicher a multi-millionaire. After the war, Streicher was
convicted of crimes against humanity during the Nuremberg trials. Specifically,
he was found to have continued his vitriolic antisemitic propaganda when he
was well aware that Jews were being murdered. For this, he was executed by
hanging. Streicher was the first member of the Nazi regime held accountable
for inciting genocide by the Nuremberg Tribunal.
