This sign says "No entrance for Poles." Signs like these led to
the propaganda and destruction of the Poles.
This is an antisemitic poster calling Jews warmongers.
"Bolshevism without a mask - large anti-Bolshevik exhibition of the NSDAP Gauleitung Berlin from November 6, 1937 to December 19, 1937 in the Reichstag Building."
The goal of this poster is to recruit Nazis.
The Nazis used lots of tricky methods to get the civilians on their side. Propaganda was more powerful than the civilians knew. But Hitler knew and it's power and it used it to make himself even more powerful. After the invasion of Poland he even had leaflets dropped that were full of propaganda.
