I just uploaded Treasure Chest Volume 15 issues 2-9 plus the Teachers Guide that came with a teacher purchased of Issue #1. There are 2 copies of Issue 2, one with the guide for Issue 2 and one without the guide.
The Treasure Chest comics I have uploaded and will be uploading are cleaned up and software enhanced copies of the ones from the American Catholic University Archives. I did this to limit the possible damage to comics in my collection.
When the Archive pages are of poor quality, which averages about 3-4 pages a comic, I am replacing with pages from my collection, providing I have a copy that will not be damaged due to scanning. Some comics from the archive are not worth cleaning up, all of Volume 5 for example. In these cases I will try to do a full scan from a copy that I have.
