Nice mirrors. Hanging them horizontally can be tricky if you're single. Vertical hanging (portrait orientation) is easy -- there's a metal bar bolted to the frame across the width of the back. However, with a horizontal orientation you have to measure out the distance between two small keyholes. The trick is aligning the nails in the wall with the keyholes. When you're single. While holding it from the front. If I had x-ray vision, it would've been child's play. Instead, I ended up buying picture wire and stringing it between the keyholes and using 2 nails in the wall (so that the picture wire stretched taut and didn't show).
