This image shows a custom accessory designed for LEGO minifigures. The item is a miniature vertical flag or banner on a flagpole.
This is a historical representation of a parade or decorative banner of the Nazi Party used in Nazi Germany during the World War II era. The design features a red field with a white circle containing a black swastika. This vertical orientation was commonly used for banners hung from buildings and displayed at large political rallies, such as the Nuremberg Rallies, serving as a powerful propaganda symbol. The accessory consists of a printed flag piece mounted vertically on a black brick-built flagpole and base.
Top quality, a bit expensive for what it is but worth it.
