Iron metal wall hook,acorn and tree leaf themed piece.Color to me looks like a drab green,but you could say its a grey or brown it's subjective to different folks.No wall hanging hardware on its back,you would attach to your wall through the openings between the leaves with a couple of screws or nails.Size it has a hefty weight,8.5 in wide at widest leaf points,depth is 2.25 in deep from outside front of hook to the back of the piece,8.75 in tall when displayed on the wall.Has a good decor look to it.
