The most popular and prolific children's author ever,Enid Blyton, continues to be highly collectable, not least through paperback versions of priceless hardback classics. A good example is 1953's'Go Ahead Secret Seven' - the fifth of the popular 'Secret Seven' series from the '40s to '60s, republished as a slim Hodder paperback with George Brook's original illustrations in 2009.
