Another Bolton NIGHTRAVEN page, this page was in Marvel's 1990 graphic novel collected reprint of the British serial.

And here's a Bolton version of the Hulk, in a 3-page HULK WEEKLY (March 21, 1979) serial for Marvel's British publications. Possibly one episode, or a whole series of Bolton HULK stories. This particular one was reprinted (in color) in MARVEL SUPER ACTION 27, Jan 1981 (along with a Barry Windsor Smith AVENGERS story, AVENGERS 66, July 1969)
And page 3 of the same HULK WEEKLY story.
