The Iconic Album Covers of Hipgnosis:

"Many classic album artists find a visual brand and stick with it. Some, like H.R. Giger, are already extremely niche. Others, like the legendary design team at Blue Note records, have the mandate of defining not only an individual album’s look, but also that of an entire record label. One of the remarkable things about Hipgnosis is their range—a characteristic that further fits with their reputation as “The Beatles of album cover art,” writes Why It Matters. “Nobody has ever done it better than the British design firm.”"
