From a recent acquisition...
You can use this reel if you want to see the comic I'm talking about
a). a sky blue edition of 500 copies (different cover, signed by Dave Gibbons plus a trading card) - this cost £7.95 in Summer 1994
b). a sunset red edition of 100 copies (different cover, signed by Dave Gibbons and 50% signed by Frank Miller) - this cost £14.95 in Summer 1994
I'm not clear if the sunset red version comes with a trading card. The trading card isn't mentioned in the ad for the comics so I didn't even know it came with the sky blue edition until I saw the (above) reel.
If you purchased either of the editions then you'd have been entered into a draw to win one of the ultra rare white editions. This was limited to just 10 copies!
Good luck tracking any of these down!
