In a weak MDF frame that can't take it's weight. It fell off the wall after 5 years so it would need to be re-enforced by having wood glued onto the back of the frame to stop the screw popping out of the mdf, or by having multiple screws to hold the wire down each side.
It doesn't fit the furnishing scheme any more here.
