RE: mounting a european mount - HELP
Look on the back of any picture frame and you will see the attachment that looks kinda' like this wwwwwwww. You can buy this type of hanger from the local hardware store. While your in the anchor section you will see screws that have a plastic anchor (this part goes into the wall) after you drill a small hole in the wall (hole has to be a little smaller than the anchor so it's a tight fit). This should work well for you and you shouldn't even have to attach it to a stud. Also the next time you put a skull on the plague just get a 3" screw and screw in into the front of the plaque. The skull can be placed over the screw to hang, keeping it from being top heavy. Hope this makes sense.
