Signs saying ‘Oblivion’ have appeared all over the neighbourhood – @nellgreco spotted this one on the corner of Campbell and Smith Streets, Surry Hills, as she walked home.

It’s obviously a take on the chalked signs Arthur Stace used to scribble out saying ‘Eternity’ – but why and who remain a mystery. Reference to the state government’s electoral hopes? New band? Buckminster Fuller graffiti?

We even had an email from Barry Divola, asking if we knew who was behind it.

I thought it might be a pessimistic 21st century response to Arthur Stace’s “Eternity”. I’m hoping that it is, anyway, and not just some guerilla marketing campaign for some new product or fashion company.

We thought it might be another bit of guerrilla advertising, but so far we’re none the wiser. Any ideas?
