Thanks everyone, in answer to the queries this one is in fact a print of an original pen and ink drawing, made by an ancestor of mine. I have several others (including the originals) which have all been identified, all were made between 1936-38, and unfortunately all over the southern half of the UK - including Boston Lincs, Dartmouth, Shrewsbury, Wells and the London area. Sorry I can't be more specific with an area but other works seem to be in this (wide) region.
