The future world of the Third Reich - a german poster from 1941

This poster was published around 1941 in "Durch die weite Welt vol. XIX", part of a book-series for boys. I purchased it from a second hand bookshop in Prague. The poster itself was created by two engineers from Munich, the writing says.

Translation of the title and the introduction:

" What new things will the technology of tomorrow bring?
Today still a venturous plan - tomorrow maybe reality

Technology and economy in the Greater German Reich have gone into an unexpected upswing. The largest network of Autobahn highways has been constructed in just a few years, whole new industries were created and great architectural and urbanistic tasks are about to be realised. Altough the war, that was forced upon us, makes it necessary to concentrate our economy on the war efforts, the great plans for the buildup are drawn with the certitude of our victory in mind. Many keen inventions and many thoughts that still seem phantastic today will then be realised. The pictures in this poster show on wich branches the engineers are working on today and what the technology of tomorrow will bring."
