Thanks Dog - that's precisely the picture I was thinking of (also appeared in the Judge Dredd Calendar last year, but in a really tiny thumbnail).
glad to be of assistance
I'm not so interested in his art style per se, just the depictions of MC-1. The architecture of the buildings, how the city looks from street level and from long distances, and the discordance between the filth and the lustrous part.
Take a look at the pic I posted above, it's a longshot of the city and, as I mentioned, there are some nice, grimy, street-level panels in The Taxidermist (also by Cam) as well as 'The Falucci Tape' from around the same era. As others have said, Midnight Surfer is like a whistle-stop tour of Cam Kennedy city scenes which, if you're able to get a look at, you'll see for yourself what we're on about.
I'd also throw Carlos Ezquerra's cityscapes into the mix too- from distant, scratchy background stuff to full blown views of a weird and fantastical vision of the future, though I pretty much love anything drawn by Carlos. I also bought a Colin MacNeil page pretty much because of the cityscape and panel layout. Like all artwork- you pays your money, you takes your choice and one opinion is as valid as another.
