Worth a visit. There's also a great photo exhibition by Stuart Roy Clarke on at the moment.
See link for some examples:
There's one great one of Deane jumping to head a clearance and punching Vinnie Jones in the face. there are also a few other references to the Blades - programme, match stub and you can see our name of the League 4 Champions trophy - made my lad smile
Have to say that there's not much about Sheffield FC or Sheffield Rules which is a bit of a disappointment given the importance of both. I wonder if the fact that it's based in Manchester has anything to do with that?
