A Sea of Swastikas

 Nazi flags fill a festival at Innsbruck. It was Hitler who came up with the idea of using the swastika as the symbol of the Nazi Party. After many attempts, he wrote in Mein Kampf, "I found a definite proportion between the size of the flag and the size of the white disk, as well as the shape and thickness of the swastika."
