Hmmm I see a listing for issues 1-8 of Graphic Story World starting in 1971 on Lonestar, then 2 issues of Wonderworld: The World of the Graphic Story (#9 and 10) starting in 1973, did it change titles? Were issues 11-16 known under a different title (or does Lonestar just not have a listing for these). I'd be curious to check these out (I love old fanzines and mags about comics), but at about $10 a pop I'm not sure if I want to pluk that down just to see.
Yes, there were name changes and the numbering continued. A few issues came out as Graphic Story Magazine. Some came out without Bill Spicer's involvement as well
