"Feeling bitter about your pint?" was the headline over this extract from the very first Good Beer Guide produced by the Campaign for the Revitalisation of Ale in November 1972. It wasn't a professionally published volume, just eighteen sheets of paper stapled together and posted out to members. It states that the Campaign supports "a really good pint" (the term "real ale" hadn't yet been coined) and the premises where it's served, and pledges to "fight against the spread of all pressurised and keg-type beers and harmful takeovers". The first properly printed GBG was published in 1974.
The address of CAMRA's first HQ in Salford was in fact the home of founder Graham Lees's mother. Annual subs were 50p (about £6 now).
