This advert was run by Reynolds some time ago now ( late 1970s we think ) . Its hung up in the workshop for all to see. There was a set of 3 posters but we only have this one left now. Mercian was asked to built the frames for this publicity run and the frame pictured was a King of Mercia . You may not know Reynolds have released a limited run of the 531 which we have a stock of if your interested.
