SG #62 came out in October 1992, shortly before Book 1, Issue 3 was finally released. As a result, SG #63, which came out in January 1993, has more about Book 1, Issue 4 than SG #62, which dealt more with Book 1, Issue 3 than Issue 4. But here's some of what can be shared from SG #62 about Book 1, Issue 3 & Issue 4:
The artwork referred to featuring Lara Parker's Lara Hoffman will be showing up before too long...
"The revelations behind the secrets of the music box will either thrill and delight people, or it'll be the cause of some very strange letters in my mailbox." I don't honestly recall what sort of comments were published in the letters column regarding what they did with the music box in Issue 4. But everyone will be able to decide for themselves long before we may get to any fan feedback...
(The really interesting thing about SG #62 is that it shares quite a bit of info about Book 2, Issue 1 - but it's way too early to get into any of that, especially because we haven't even decided if we're going to do a slideshow for Book 2 (though as I've said, in my opinion, it's a better story...).)
