An original double sided enamel Lyons Tea sign. 
Both sides have suffered some damage over its lifetime and somewhere along the way it has had some repairs made to the damage. 
Still a good example of an original advertising sign and very decorative. It can still be fixed to the wall by the flange on the side which has been painted previously with what seems to be a rust protection paint. 
Measurements: 38 x 23cm high.
