THIS selection of largely Edwardian postcards of Darlington and the surrounding area is taken from the latest book compiled by local deltiologist, Araf Chohan. Araf comes from Middlesbrough, and has been collecting postcards - deltiology - for many years. Last year, we featured his first book, on the St Hilda's area of his hometown. His new book, Darlington and Surroundings in Old Postcards, costs £9.99 and is available from Waterstones in the Cornmill Centre and the Head of Steam museum, or through the website of its local publishing company, destinworld.co.uk
