That sounds strange, so you are not missing any pages in the back as well? Or are the pages blank? If the problem is with the binding you would miss 2 in the front and 2 in the back as those are printed on the same (missing) paper.
There's no problem with my copy. The content is:
Cover - 1 page Contents - 1 page The Incredible Quest for Cooties - 27 pages No Sail - 1 page Suds in Your Eye - 9 pages Crosstalk - 1 page From the Publisher's Desk - 1 page On sale this month - 1 page Uncle Scrooge hardcover ad - 1 page Comic Everywhere (digital comics ad) - 1 page
Got a complete copy of DD#11 at my comic book store. I would like to thank y'all (especially Joe, whom looked into this for me off the forum) for your help. Happy readings everyone.
