The rear of the printed metal in this photo has the floating hangar option, but there are other display options as well.
Pricing will depend on the size, and display option, and it's not cheap compared to canvas, for example. A 8x12in photograph (20.32x30.48cm) with a floating hangar display option costs $100. Still, the results are stunning and it's worth checking out if you want something different to hang up on your walls.
