Haha, I'm guessing that's some program to artificially "age" images? I'm pretty tech-challenged.
The back cover is a photo of a long line of bobbies lined up along the edge of the pitch at a football match riot, taken by our drummer from roughly the same period, but in England.
Thanks for lookin fellers.
I suppose eventually hipsters will have their photos painted over to look like Norman Rockwell paintings and ultimately have their photos look like cave drawings. Can't get much older school than that.
