Their Wikipedia page contains a wealth of information and a list of the albums they worked on. I have a great many of them.
I have this book on the agency which I bought at the shop at the V&A Pink Floyd exhibition of props and other items. It contains a complete collection of everything they worked on.
They designed this logo for Led Zeppelin in 1973 for example.
They created a range of familiar logos and other imagery that will be familiar to music fans (particularly those of a certain age i.e. old like me).
In 1974, they redesigned the Genesis logo for their work on 'The Lamb Lies Down on Broadway'.
I used to have this as a badge on my Italian combat jacket that was all the range back in the early 1980s and which I used to wear all the time.
