The UK 7" for Running Up That Hill had two releases. The first was a standard single issue picture sleeve, and the second was a gatefold picture sleeve. The gatefold release does differ from the standard release in a few ways. Although both have the same artwork on the front of the sleeve, the artwork on the back of each is completely different from one another.
When you open the gatefold, two additional photos are found inside. The second photo is actually the one that's used on the back of the standard release.
The record slides out from a pocket on the right-hand side of the sleeve, and the single is exactly the same as the standard release, so it doesn't differ in any way. The other interesting thing is that both releases have the exact same catalogue number.
