Although both the 12" and the 7" feature the same artwork on the front and back, the back of the 12" release features an additional photo of Kate from the video, which is not found on the 7" release.
The 12" also features the Organon Remix of Cloudbusting. Most of the UK 12" single sleeves from the Hounds of Love era are also pretty flimsy. This sleeve is no exception.
The labels on this release are purple. However, there is another release with the black labels as well. Unlike the 7" single, which has an inscription on the run off vinyl, it's not to be found on the 12" version.
