Hi! I just posted a similar thread over at the DCM site, but it's probably even more appropriate here, considering the Silver Age vintage of the books in question.
At this weekend's San Diego Comic-Con, I purchased two Charlton books from 1960 in a random bin of $2 clearance comics. They both have identical covers identifying them as "Brides in Love #18". However, not only are the interior pages different, they're not even romance comics! The interior of one book is a Western, and the other one is war stories! (I've posted
snapshots of the book covers and interior splash pages online over at my personal blog if anyone wants to take a look.)
The legal text on the inside front covers has the typical Charlton lack of proper copyright notice, and would thus be free to scan and share on the site. However, considering that the contents of the books are unrelated to their covers, I'm not sure how I'd categorize those uploads even if I scanned them.
(Someone at the DCM board helpfully identified the interiors as probably coming from "Outlaws of the West #25" and "Fightin' Marines #35". Perhaps I should just scan the books as if they were coverless copies and post them as incomplete additions to the Charlton Silver Age section here?)
I've seen Charlton have quality control issues regarding the print quality and page trimming on a lot of their books I've seen, but this is my first encounter with them packaging the wrong books under wrong covers. I'm curious if anyone else run across this sort of misprint before?
