Yeah, that's what I've been thinking. I was curious to see if anyone on the board thought the same.

Looking at the picture, is there a cross member to the frame at the bottom of the arch? If so, that's where I would secure either the hangers in your first or second picture--across the horizontal member. All stress will be perpendicular to the anchor (nail or screw) with less likelihood of pulling out. If there is no cross member, then use the hangers in either the second or third picture, and mount them separately to the wall--could be a PITA to get level. You could also use a flat stock piece of aluminum running horizontally, secure it to each side, and mount the aluminum bar, level to the wall.

There isn't anything at the bottom of the arch on the back. The mirror itself is the shape of the thing. The only place that's not mirror is a 3" rim around the perimeter. I like the idea of the flat stock. I could maybe even run 2 pieces up each side, and then mount another piece to those two, that way the whole thing would be attached at several points down each side.

thanks.
