I haven't posted one of these for a while, and this is a goodie! 2000AD Prog #196 by Dave Gibbons. As a recap about the process; The black & white line art has been printed onto an acetate overlay and a duplicate of that has been printed onto a separate sheet in blue line. The colours have been hand painted onto the blue line sheet and the two are married together before being sent to press. This is how things were done in the Command Module, circa 1981!
