Great Item!!
Mick Jagger, Keith Richards, Charlie Watts, and Ronnie Wood signed this Dirty Work album for me in person in Toronto, Canada in September 1997. The Stones were in town rehearsing for their upcoming Bridges to Babylon tour. 
Mick, Ronnie, and Charlie autographs are  strong and look fantastic. The Keith Richards autograph, as you can see above is very "light".  Keith signed this album in a light rain fall that evening and it's just the way the ink came out. You can obviously still see it but it is very light compared to the other autographs. 
The actual album cover is in overall good condition however there is some wear and creases. The most noticible crease is in the bottom right hand corner by the Watts autograph. As you can see by the pics above it overall looks great.  
This is a fantastic item.  Please feel free to email me any questions. I will also include the two pictures I took a Mick and Ronnie signing that evening ( pictures above). I will also including the actual Dirty Works vinyl record album with this auctions. 
Good Luck!
