We have a selection of British Rail signs for sale. Price is per single sticker. These are genuine and are permanent if you use heat to stick them onto a wall or window. The No Smoking and First Class stickers have the same design on both sides and are intended to go onto glass.
I can provide a certificate of authenticity if required.
The proceeds are going to a train restoration project (a 4-BEP unit) if you want more information, please get in touch.
