Each of the books are in PDF format and contain anywhere from 24 to 68 pages of Golden Age comics, augmented with new fiction, roleplaying game rules, and/or biographical material about the creators. From now through Saturday 3/7/2015, most of the comics are on sale for 30 percent off the regular price, so now is the perfect time to check them out. Some of these comics have never been collected in one place before, and few have been reprinted since they originally appeared in the 1940s and 1950s.
