Sure it's just a sign. Much like any sign really.
It carries the name of a famous Australian artist. No surprises there.
It states what the sign means to name. That's what signs do.
It's read by thousands of people daily but few have ever really seen it. The mark of a good sign.
Just a sign perhaps but today I made it a portrait.
