This beaten copper mural by an unknown artist apparently depicts the history of Brunswick Street from 1890 to 1970.
With New Farm on the left and Fortitude Valley on the right.
The plate says it was commissioned by the National Australia Bank in 1972, and it was displayed at the bank until the 1990’s.
Queensland Rail purchased it in 2004, which is why I guess it is now displayed on one of the platforms at Fortitude Valley railway station.
Shame it’s not possible to get a little closer to it, to see the details.
