The Gooderham Building is well known for the mural on its back wall. The Mural by Canadian artist Derek Michael Besant uses a trompe l'oeil effect to not only make the wall appear to have more windows than it does, but to also gives it a more motion effect by having its edges 'fluttering' away, where they are not 'tacked' down.

The red-brick Gooderham Building is a historic landmark of Toronto. Completed in 1892, it was an early example of a "Flatiron" building. It was built by architect David Roberts, Jr. and originally cost $18,000. Sold in 2011 for bit more - $15.2 mil.
The mural ($93,000) was paid about 80% by private companies and the rest by the city. The artist was paid only about $8,000, yet more people see it, than some million dollar painting.
