bring back nostalgia and memories
Well, your description is a bit confusing. You mixed pictures from the "Weimarer Republik" (1919-1933) as well as pictures from the former GDR (1949-1989) with actual pictures of Hitler's Germany (1933-1945). Fortunately all pictures are marked with a date which makes iteasy to put them into the right era.
May I suggest you remove the pictures that are out of time?
