Sure. The term “commercial scale” can vary, depending on the goods we're talking about. Here we're talking about artistic works. If we're talking about copies that are reproduced in a fairly significant number for the purposes of being distributed and sold in the marketplace, that would be work reproduced on a commercial scale.
If someone takes a picture and then has it reproduced in thousands of copies to be sold at Vancouver Olympic venues as a postcard, that's definitely reproduction on a commercial scale, as opposed to an original painting by an artist in downtown Vancouver that would not be reproduced.
