I just looked at this mirror in the store yesterday. It has hardware already (metal loops, screwed into the back of the mirror) to hang it either vertically or horizontally. Basically, you would fit the loops over hooks or screws (not supplied) on either side of the mirror, which you would put into your wall for this purpose. It would be like hanging a picture frame. You could alternately use frame hanging wire, which could be secured to the loops on the back of the mirror. Finally, a more permanent approach would be to remove the hardware from the back of the mirror, and attach the mirror to the wall with contact cement of some kind. The person helping me in the store suggested that if you use this method, you might also want to put an L-bracket at the bottom of the mirror to provide further support. (You would also need to have some method of holding it in place while the cement hardened.)
