Peter Saville's radio pulse-inspired artwork for Joy Division's seminal album was borne from the 1977 edition of the The Cambridge Encyclopaedia of Astronomy; science has never been so cool.

The scientific drawing itself was compiled by Dr Harold D Craft Jr in his 1970 thesis Radio Observations of the Pulse Profiles and Dispersion Measures of Twelve Pulsars. It was this drawing that drummer Stephen Morris brought to Saville's attention.

The rest is pop history...

Allegedly, britpop band began dotting the ‘J’ in James with a daisy on the cover art of the 1990 release of single Come Home after manager Martine McDonagh decided that their name alone was ‘too boring’. After this, the simple logo became synonymous with the band, even dominating the sleeve of their ‘Best Of’ album in 1998.

Peter Saville, designer of iconic record sleeves for bands including Joy Division and New Order, joins Steve now.

Here's a selection of renowned designs by the Factory Record's co-founder.

The iconic Dark Side of the Moon artwork was produced by Aubrey Powell for Hipgnosis, a prolific design trio completed by Storm Thorgerson and Peter Christopherson, who were responsible for equally enduring designs for Led Zeppelin, AC/DC, Black Sabbath, Genesis and many more.

Already friends with Powell and Thorgeson, the band approached them about the artwork, but were pretty firm about not basing the design around photography, preferring a more graphic-based idea.

England designer Joe Petagno has worked with seminal music art group Hipgnosis on projects ranging from Pink Floyd to Led Zeppelin. His first collaboration with Motorhead was creating ‘Snaggletooth’, the wild boar that forms the centre-piece of much of the band’s distinctive artwork, for their debut self-titled album. The same ‘Iron Bear’ appears on the England design.

The presidential seal that dons this classic rock T-shirt has arguably introduced The Ramones to a whole new audience – the younger generation seeking out the origins of the fashionable artwork. It was the work of the late designer Arturo Vega, who once told the writer Jim Bessman about its origins.

It’s thought that singer Kurt Cobain drew the smiley face design of this ever-popular T-shirt that's worn by long-time devotees and teenagers alike. In 1991, the simple line drawing appeared on a flyer for the Nevermind album launch party – around the same time T-shirt was first made available.

(And just in case you’re interested, the writing on the T-shirt uses the Onyx typeface.)

Guns N Roses artwork for their debut LP Appetite for Destruction was built to last by tattoo artist Billy White Jr, who incorporated the skulls of each member on a gothic cross. But it could have been a different outcome for rock history - the original design planned for the release, which you can see on the NME website, external, was a far less chest-friendly affair!

The only surviving original member of Sisters of Mercy, Andrew Eldritch, produced the design for his gothic rock music by combining a mystical pentagle symbol with one of anatomist Henry Vandyke Carter’s drawings for the 1858 medical textbook, Gray’s Anatomy. This scientific source of inspiration is still published to this day, just as Eldritch’s T-shirt design is still distributed.

Raymond Pettibon’s artwork for the sixth Sonic Youth LP Goo was inspired by a 1966 paparazzi image of Moors murderers trial witnesses Maureen Hindley and her first husband, David Smith. You can see some of the parodies it would go on to inspire on the Buzzfeed website, external and take a look the photograph that inspired the Pettibon’s artwork here, external.

Paul Cannell created artwork for the Manic Street Preachers’ You Love Us as well as the cover art for Primal Scream’s Mercury Prize winning LP Screamdelica. In 1992 the artist told Select Magazine that singer Bobby Gillespie had been seeking artwork for single Higher than the Sun that was ‘jazz’ and ‘abstract’ - but wouldn’t play Cannell the music itself. Thankfully the collaboration was so successful that the design would be adapted to promote Screamdelica and the single Don’t Fight It, Feel It.

Cannell was inspired by artists such as Picasso and Renoir, but also developed his unique style from painting and drawing with his right hand - despite naturally being left-handed.

It's the final 60 minutes of T-shirt Day 2015!

Still to come, designer Peter Saville will be joining us to talk about what makes a good design.

And of course we'll be running through the top ten T-shirts. 

We've had this email detailing a traumatic crime against a music fan's wardrobe. Matt from Preston, we hope you find new T-shirts soon to fill the void. Today has hopefully provided plenty of inspiration!

Based on the 1977 Silver Jubilee portrait by Royal photographer Peter Grugeon, the Sex Pistols' image just misses out on a place in the top ten.

Playing now, to match the royal theme, is God Save The Queen.

Rumour says that Inspiral Carpets sold more copies of this T-shirt than all their albums combined. 

Saturn 5 is the track that's playing live right now.
