Eternity (graffito)
The word Eternity was a graffito tag that was written in chalk on the streets of Sydney, Australia about half a million times between 1932 and 1967. The identity of the perpetrator remained unknown for the first 24 years until he was identified as Arthur Stace, an illiterate pipe layer and evangelist Christian. Stace was a former petty criminal and alcoholic who started writing Eternity as his "one word sermon" after he converted.
