In my continuing exploration of the vast information universe that is the Internet Archive, I have only just recently entered the Texts area. Among the unbelievable variety of scanned texts, I found a number of comic books, ranging from "Golden Age" commercial titles including Superman's Pal Jimmy Olsen, Red Ryder, Roy Rogers, Tarzan, and Zorro to comic publications by the U.S. Government and religious organizations. The commercial comics include all the advertising for those must have items (like X-Ray glasses). You need to download CDisplay to view them, but it is a quick, easy and free download. They are not all in one designated comic book collection, so just search the Text area for "comic book."
