I have Uncle Scrooge #354 and no pages are missing in my copy. I have the whole issue from the first page to the last page.
My copy is intact, as well. I have to ask, Charlie Brown, given that this is an old book, how come you're only noticing this now? Did you just buy this issue as a back-issue? I would imagine that this is grounds for returning it and getting a replacement or your money back.
