Thanks everyone! It would have taken me ages to scan and edit this collection by myself. It's great to see Don's collection being preserved and shared like he would have wanted.
Just FYI, we'll probably run into several examples of the newly scanned comics from Don's collection matching partial scans already on the site. For the past few years, Don had scanned individual Captain Marvel Jr stories from his collection to reprint on his "Blue Boy" blog, and these pages were eventually reposted here as incomplete issues. I'm so glad to see the full issues finally being scanned. Thanks again to everyone who has helped so far! (More books still to come!)
