Also, the image here upright is the pegan germanic life/protection rune. Upside down ( looks like peace symbol) is the death rune.

More on what we use as the peace symbol: "When the two elements of Yr and a circle are placed in their relative positions, it is telling of the death of an unborn child and though not explicitly stated by Russell himself, can be construed as a parallel to the disbelief of the second coming of Jesus, which Russell believed to be the only way for mankind to converge and progress as a species — a sentiment reflective of that of the great Age of Enlightenment that followed the Renaissance."
