I bought an oak antique wall cupboard. It's very large, a metre wide & 1.5m high. It's got a heavily carved front with a garland of flowers hanging down from carved bows - so it has a definite 'right way up'. The bottom edge is carved in a semicircle, so it can't balance & lean against the wall. There are absolutely no fixings on the back. No holes, no metal plates, nothing. Just a flush plain back. How was it ever hung on the wall?
