A few suggestions:
(Salon de )
Submissions that have been refused or rejected from other corporate, government or community exhibitions (or purchases).
The Naked City
A exposure of the realities of urban life and the cityscape.
Images that reflect on world terrorism and its effects
A good excuse for a combined/exhibition/musical event party
A battle of bands(paintings) between abstract and figurative images
Images that reflect on political (and parliamentary practice in Canada)
