Notable examples are The Beatles Sgt. Pepper's Lonely Hearts Club Band which had cut-out inserts, lyrics, a gatefold sleeve though a single album; and Pink Floyd's The Dark Side of the Moon which had gatefold, lyrics, no title on the sleeve and poster inserts. The move to the small (less than 1/4 the size of a record) CD format lost that impact, though attempts have been made to create a more desirable packaging for the CD format, for example the re-issue of Sgt. Pepper, which had a cardboard box and booklet, or the use of oversized packaging. The importance of cover design was such that some artists specialised or gained fame through their work, notably the design team Hipgnosis (through their work on Pink Floyd albums amongst others) and Roger Dean famous for his Yes and Greenslade covers. A number of companies specialised in the manufacture of album covers. In the UK, for example, Garrod and Lofthouse were the leading company - the G & L mark was seen on the majority of albums at the time.
