I can't remember whether I ever definitely bought a ROM comic or not. I have a feeling I may've bought either the last issue or an Annual, but I couldn't swear to it. If I did, I'll still have it, so maybe I'll find it tucked away in a cupboard one day. I also have an inkling that I may've read some of his adventures reprinted in b&w in a Marvel UK mag, but can't recall which one.
One thing I do know is that I never bought the first issue, but now, thanks to Marvel's superb series of Facsimile Editions, I own it now as it popped through my letterbox this morning (Friday). Haven't read it yet, may not do so for a while, but good to have in my collection nonetheless. (And it's got the 'Continued After Next Page' lines before the ads.)
So why not run around to your local comicbook store and obtain a copy for yourself? You'll only regret it if you don't.
