“The artwork, done by Peter Saville, is based on a poster by Italian Futurist Fortunato Depero for the 1932 exposition Futurismo Trentino. Saville adapted it so that the ‘F’ stands for Factory and the ‘L’ (Roman numeral) for 50. The album colour in the UK was blue with blue artwork, while in the US it was white with burgundy artwork.” — Discogs
One of my all-time favorite album covers. I also love the carelessness of a band accused of being neo-Fascist because of their name having a Futurism-inspired cover on their first LP. Glad to finally know what typeface Saville used!
