Hey everybody. I have quite a comic book collection (8,300+) and there are a number of pages in my collection that I think you'll find relevant to your interests. They are to mine!
Monkeyman and O'Brien was a pretty cool comic created by Arthur Adams in which a machine brings a ten-foot-tall, hyper-intelligent ape named Axwell Tiberius. Ann O'Brien is near the machine when this happens, and exposure to... something causes her to grow to a height of seven feet and become strong and muscular. That's not all, though - there was once a story where she just kept growing and growing, and I'll get to that. First, I've scanned the pages I think are relevant from the origin story. These are the ones attached to the post.
Now, on to the Giantess story. It goes as far as any one I've ever seen (space and so forth). It's from a series of free "newspapers" Dark Horse used to print with strips of their popular series. It was supposed to be a lark, so it is an incredibly silly story, but it's fun and she does grow like crazy. You can actually view it
here in psuedo-animated form circa 2000, but I tried to put it into a more permanent form for us. Because of zooming and panning on that site, it wasn't easy to make static pages, so forgive a bit of sloppiness.
I seem to have hit an upload limit, so see this story on my photobucket album
