One of my all time favourite 2000AD strips is Glimmer Rats. Written by the legend that is Gordon Rennie and drawn by Mark Harrison it really is a great story and a feast for the eyes.
I picked up a couple of pieces of the art from it on EBAY somehow a few years ago and they are gorgeous sketches what have been water coloured in black and grey. I think. Take a look I hope you like them and if you can you should pick up a copy of it because it is freakishly gorgeous.
