I have been collecting and dealing telephones for many years and never found one like this before. It is a double sided sign with two hanging holes in the top. The side shown is by far the better one and although not by any means perfect it is bright and clear.
This one is in my collection and I am happy to leave it there but I would sell it for £350. This may be one a collector has been searching for or simply had no idea of its existence.
