Well I'll be !!!!!
There it is.
From everything that was said in The Kirby Collector & elsewhere--it was assumed that the only thing missing was about 10 panels from various pages. I'm having a little trouble reading it but it looks like either page 3 or 7.
I wonder if this was a case of Kirby not being aware of, or not remembering that they needed 18 full pages and 2 'half' pages during that time and drawing 20 by mistake. Perhaps they dumped that page even before shelving the book for those months.

very cool!
