We've received a few previously unknown pages since we started. If things continue at the same rate, there's a very good chance that more pages will turn up.
Peter Jones sent in page 20 back when we were still attempting to assemble the story only from the original art.
A
very fuzzy page 7 was published in
Alter Ego - reproduced from an illegible photo, the only copy of the page known to be in existence. But after we started the reconstruction project, we received two exclusives from Thomas Andrae - a very clear and legible photocopy of page 7, and of the never-before-seen page 12.
There are a lot of people very curious to see the original page 26. Although the mysterious metal from Krypton is called "K-Metal" in the last page of the script (the only place in the story that it's ever actually named), there is some speculation that it could have been changed in post-production to "Kryptonite."
But I don't buy that - everything we've found to date is word-for-word what's in the script - grammatical errors and all.
