It states that issue 2 was published in August of 1992, and that the publication schedule was erratic. So maybe the first one came out in June
I'd have to dig out my ShadowGrams from 1992 to be sure of exact release dates. But I keep my issues in the envelopes that Innovation mailed them in and Book One, Issue One is postmarked April '92, while Book One, Issue Two is postmarked July.
Only the first issue of the third "book" was released when Innovation, the publisher, went out of business. I wonder if the complete storyline planned for that "book" was ever posted online.
SG may have given some indication of where Book Three was to be headed. I believe they may have also shared some unpublished artwork from Book Three...
Despite their disclaimer, the comics do seem to make use of material from the original series that weren't a part of the Universe of the 1991 iteration. For instance, in one story, Liz warns Vicki not to set foot in the basement, and Carolyn asks her what she's hiding, to Liz's displeasure. This idea of Liz keeping the basement locked up and warning people away from it wasn't spoken of in the 1991 episodes that I saw, at least, I don't recall it ever being mentioned.
No references to staying away from the basement ever came up on the '91 Series. And I believe what Innovation's disclaimer may have actually meant was that unless they introduced any elements from the original show into the comics, those elements from the original show didn't exist in the world of the comics. However, one thing I do know for sure is that they stated that if they "borrowed" any elements from the original show, they planned to take them in different directions, so essentially they wouldn't be the same as what took place on the original show. Though we'll never know if they would have stuck to that or not. But another thing I do know is that Innovation definitely planned to reveal that Liz was Vicki's mother...
