It was listed by Culvertons. Sold pieces stay on Sellingantiques as a record of what has passed through, and the next one is rarely far away.
Culvertons has dated this Cast Iron Warning Sign to the 19th Century.
For a very interesting article about early signage for cyclists, by a CTC Winged Wheels member, please click on this link - https://www.cyclingnorthwales.co.uk/pages/ctc_wing_whls.htm . I have included an image of the sign prior to it being repainted, and you can just see remnants of the original red base colour. A coat of red oxide was painted on to the sign's surface before applying the top coats. A very scarce and decorative sign.
