I think Acrylic Afternoons (acrylicafternoons.com) has a scan of the map in its Press archive. You'll just have to search through the archive a bit... which is not a bad way to waste a lazy Sunday afternoon.

If you want a hard copy of the map, you'd do best to look for the NME Britpop Special Collector's Issue that they put out a few years ago. It should be easy to find.

Not a map per se, but you might find this helpful: http://www.pulppeople.plus.com/Sheffield/sheffield.htm
