I recently received an email from someone willing to scan in those four pages, so they should be up soon. The contributor wishes to remain anonymous, but I'm extending thanks anyways.
In the meantime, here are the few pages that were reproduced in Alter Ego:
Of the four comic pages reproduced in The Steranko History of Comics 1, only two page numbers are legible: 15 and 21.
Page 15 continues the typewritten scene of PAGE 14 beginning in
Professor Barnett Winton's residence and continues on into the Professor's laboratory (on page 15):
NARRATOR: "Before Clark's surprised vision, the Professor wheels out a great metal container..."
CLARK: "Inside that container..?"
PROFESSOR: "The metal. The strange metal I told you of."
next panel:
PROFESSOR: "See! It glows with a penetrating green brilliance! Strangely enough, it was dull only until the fragment from KRYPTON approached Earth. Then came this new luster."
CLARK (thinks): "That unaccountable weakness again..! Then it seems this metal too hails from KRYPTON!"
it's possible Clark said the second line out loud... hard to be sure as the panel is very small and poorly reproduced
next panel:
PROFESSOR: "And what strange powers this metal imparts! See -- I touch it... and tho I am a feeble old man, suddenly I find myself possessed temporarily of tremendous strength! -- You try it!"
But of course, when Clark tries it he cries out in pain and collapses unconscious.
Page 21 is the sequence in which Clark, trapped in a sealed mine with a bunch of people (who seem to be the bad guys) and Lois, reveals his secret identity to everyone present in order to save them.
As to the other two pages, the first one shows Superman being knocked down and hurt by a car driven by a drunk driver! The other shows Superman, with Lois in his arms, finally confronting the villain, Bronson.
LOIS: "This is the first time I've seen you doubt your own ability!"
Great Rao:

Great! I hope you are somehow able to increase the size of the pages so they can be better appreciated. As India said, detail has been lost -- some restoration work might be possible by someone with a careful hand...?
