Sounds nice, but I wonder if a "bricks and mortar" style of gallery, rather than an exclusively online exhibit, is really a good idea in this day and age. I suspect that most visitors, especially younger ones, would spend most of their time taking photos of the photos and then looking at them later on their cell phones. I like public spaces and galleries, but I find that I am increasingly enjoying the experience of looking at old photos of Canada that I can access online through various facebook history groups and other sites. And with my large monitor, I can often get closer to the details of the photo that i would be able to in a public gallery. Why not scrap the idea of a physical gallery and simply put the resources into the online version, and have a physical archive so that the actual photos are protected for posterity?
