Reznor stated in one of his posts on the Prodigy internet service in the early 90s that "the cover of PHM is a photo of the blades of some sort of turbine stretched vertically so they would look somewhat like bones or a rib cage."[http://www.theninhotline.net/archives/articles/manager/display_article.php?id=327] [[The NIN Hotline]] shared in 2024 that the machine in the image is likely a 1930s inline diesel engine.[https://www.theninhotline.com/news/permalink/1729481140]
In an interview with sleevage.com (later reposted to Patreon[https://webwww.archivepatreon.orgcom/webposts/20101101052703/http://sleevage.com/ninin-prettydepth-hatenins-machine/ Sleevage.com30900269]), [[Rob Sheridan]] described the long process he went through to update the artwork for the 2010 re-issuereissue:
<blockquote>
When we began the ''Pretty Hate Machine'' remaster project, Trent discussed with me the idea of tweaking the original artwork a bit to reflect that this was a different version of the album, updated from its original release. We talked about maybe just changing the color scheme a bit – Trent was keen on losing the distinctly 80′s hot pink color, for one. It seemed like a fairly straightforward project, as I certainly didn’t want to try and radically alter an album cover I’d been looking at since I was a teenager, and that some fans had known very well for more than two decades.
