On offer is this very rare vintage ashtray, dating I am led to believe from the Twenties. Produced to promote READ BROTHERS of LONDON,, and their DOGS HEAD BASS and their, DOGS HEAD GUINNESS STOUT. Made of metal, or tin plate, with a GLASS INSERT, in the middle. Trust me this is an extremely rare ashtray, and is out of my collection. Limited space forces a reluctant sale . Bidding on this very desirable piece must start at £85.00. For its age and type I would class this American ashtray, as being in good nick. The approx. diameter of the item is 4.25".
