After Stalingrad, the Nazi intensified their "total war" measures. On 5 June 1943, Albert Speer and Joseph Goebbels addressed a mass meeting of armaments workers in Berlin, at which Speer claimed enormous increases in German armaments production. I've added a translation of his speech. The speech Goebbels delivered was already on the GPA.
The illustration is the cover of the pamphlet containing both speeches.
