From • @factoryrecordsfans The first use of the image on the cover art for "Unknown Pleasures" originally published by Harold Craft in his 1970 PhD thesis "Radio observations of the pulse profiles and dispersion measures of twelve pulsars". Page 215 shows 80 successive pulses of the first pulsar observed, CP1919, tastefully stacked on top of one another. The plot was subsequently reproduced as a white-on-red image for the cover art of the 1970 International Astronomy Union General Assembly "Highlights of Astronomy" edited by Cornelis De Jager, as a white-on-black image in Walter Herdeg's 1974 "Graphis Diagrams: The Graphic Visualization of Abstract Data", and then in the black-on-white style in Simon Mitton's editing of the 1977 edition of "The Cambridge Encyclopaedia of Astronomy. #factoryrecords #factoryrecordsfans #Russellclub #hulme #manchester #manchestermusic #punk #postpunk #postpunkmusic #darkwave #newwave #joydivision #joydivisionforever #shoehaze #goth #joydivisionfans #iancurtis #thehacienda #fac51 #tonywilson #peterhook #stephenmorris #bernardsumner #petersaville #unknownpleasures #martinhannett https://www.instagram.com/p/CetU8AhjImC7VA2BG5JgSijFWHQkdHQ8cy8kX00/?igshid=NGJjMDIxMWI=
