The sleeve was the work of Dutch photographer Anton Corbijn, who travelled across the California desert with U2 over several days chasing a single brief: desert meeting civilization, resolution in the face of desolation. The concept came first, under the working titles The Two Americas and The Desert Songs, an attempt to hold the band's love-hate relationship with America inside a frame of sand and ghost towns.
The album's name arrived on the journey almost by accident. On the evening after the first day's shoot, Corbijn told the band about Joshua trees, the spiked plants of the Mojave, and suggested they include one. The next day Bono declared it: the album would be The Joshua Tree, its Biblical weight sealing the choice. On the second day Corbijn spotted a single tree standing alone off Route 190 near Darwin, a rarity since the trees usually grow in clusters, and the crew photographed it for roughly twenty minutes before moving on. Those images became the inner shots. Corbijn worked with a Russian-made Horizont panoramic camera, his first time using it. The front-cover group shot itself was made not inside Joshua Tree National Park, as many assume, but at Zabriskie Point in Death Valley, over two hundred miles from the lone tree.
Steve Averill, the Dublin-born designer who has shaped every U2 cover from Boy to Songs of Innocence, art-directed and built the sleeve around the landscape. He described the theme as desert and ghost towns, places where nature and civilization collide, and traced its cinematic eye to directors like John Ford and Sergio Leone. Averill also mocked up prototype covers, including a landscape-only design without the band in the manner of an ECM jazz record, before the group settled on the cinematic shot.
Released on 9 March 1987 by Island Records, the album marked U2's turn toward American and Irish roots, blues, gospel, soul and folk, away from their earlier ambient post-punk. It was the first U2 album issued simultaneously on twelve-inch vinyl, five-inch CD and cassette, each format carrying a slightly different version of the cover image.
