Welcome to the wonderful world of British 45 rpm record company sleeves! This impeccable reference book features over 900 sleeves dating from when the 7 inch record was introduced in the UK at the end of 1952, right through to the end of the 1980s, after being taken over by the picture sleeves. All these ageing pieces of paper, of which a number are getting increasingly difficult to find, are presented here - for each label in chronological order with the approximate dates of their life span. Each sleeve has its unique reference number which makes them easy to compare.
