The mirror does rest on the white molding at the top of the wainscot and there is a space between the picture and the wall. That top molding is about 1-1/2" thick so we had to mount an equally thick piece of wood on the drywall surface and then we hung the mirror from that. We attached heavy duty picture hooks to the wood spacer and hung the picture using heavy duty picture wire. You could also look up "French Cleat" and the picture could also be hung using that method.
