This article published a few days ago in The Economist is about an art exhibition which is currently showing in London. It includes paintings of Tom Roberts, Arthur Streeton and Charles Condor. One of Streeton's paintings, called "The National Game" is of an AFL game but appears to show only goal posts. Which makes me wonder...when did behind posts become part of the game? I think "The National Game" was painted in 1889. Here's that picture. Anyone know when behind posts were added?
