"Tag der Deutschen Polizei 1941" or "Day of the German Police 1941": by the German artist R. Seyfried, who unfortunately I know nothing about. They were also done as postcards that came in a commemorative pack. "WHW" stands for "Winterhilfswerk" or Winter Relief - literally "winter help work" indicating they were used as donation tools to support the Police fighting in anti-partisan duties behind the Army.
Flak-Kanoniere of the 2. SS-Panzer-Division 'Das Reich' wave a flag to alert the Stuka pilots above them of their position at the frontline in the region of Belgorod, Russia. In the left an Sd.Kfz. 10/5 carried the 2 cm FlaK 30. 3 August 1943.
World War II in colour - England, circa 1945 Ace American pilot Lieutenant Colonel Francis S. Gabreski poses in a cockpit. The flags refer to the 28 enemy planes brought down by Gabreski. If you look closely above the swastikas it names the type of plane shot down.
