I was shown a pamphlet one time that the peace symbol (chicken foot) was really the broken Cross of Jesus Christ. I don't know if this is true or not...just my 2 cents worth. I have never liked the peace symbol.
This will sound rather strange, but the symbol itself was supposed to represent a nuclear bomber. There's a painting from 1963 (the time of the ban the bomb movement) called "Leopardskin Nuclear Bomber No2" by a Colin Self which if you look at it has the same profile of the portions of the symbol inside the peace sign's circle; evidence that the symbol represented a bomber with swept back wings.
