It's from HULK (formally THE RAMPAGING HULK) issue 24 (December 1980). Predictably, it also contained an article on the TV show (which *may* have been recycled somewhere by Marvel UK, probably (if anywhere) in an issue of RAMPAGE) which I've also posted.
The editorial to this issue is interesting. Ralph Macchio (nope, not that one) explains that - to keep the magazine viable - they've had to abandon the colour interiors on the main strip (but retain them for the back-up strip). That's honesty you have to admire.
