FMP - display problems

My initial idea for display was to have the old photograph on top of a bigger canvas (referenced and titled) and then have the re-photographed image below. At first, it seemed like a good idea and a classic approach but at a second thought, it seemed too mundane. Another idea is to use a slider and have the old image at the back and the new one in the front and have people slide back and forth to see the difference. This is a common approach in editing software commercials but I had no idea how this would be achieved in an exhibition, since I do not aim for simply online exposure (the Internet is vast and information is easily lost or hard to reach the right audience without too much money invested in promotion). In addition, I needed to figure out what places I need to photograph.
