Personal standard of Adolf Hitler

The Standard of the Führer (German: Führerstandarte or Standarte des Führers) was a square red banner of arms with a black swastika on a white disc inside a central wreath of golden oak leaves and four Nazi eagles in the corners, associated with the office of the Führer (leader) of Nazi Germany (a title which in practice was only held by Adolf Hitler). It typically indicated the presence of Hitler at official events and was displayed in the form of a hoisted flag, small car flag, and so on.
