Goya's 1803 painting of "The Peasant Before the Firing Squad" served as an inspiration for what symbol?

The peace sign:

[Designer Gerald] Holtom later wrote to Hugh Brock, editor of Peace News, explaining the genesis of his idea in greater depth: "I was in despair. Deep despair. I drew myself: the representative of an individual in despair, with hands palm outstretched outwards and downwards in the manner of Goya's peasant before the firing squad. I formalised the drawing into a line and put a circle round it."
