Something that became quite a fashion when we were eighteen or thereabouts was tracking down what you might call pulp fiction. I remember 'Cosh Boy' particularly well because it had a garish cover featuring, I think, Joan Collins. Ace and Four Square published a fair few of these, at about a shilling and sixpence each. The more lurid the cover, the better we liked it; particularly if it had, say, stockings and suspenders. 'Espresso Bongo' was slightly less cheesy, having been turned into a successful movie. Some had a Soho flavour to them and had been rated as semi-porn in their day. Anyone remember them? I bet Beatnik's Ghost does. Paul?
Slim Jenkins is a fan of the genre, I believe
