Let's take a look at where you can read those tales more recently!
More Fun with Dr. Fate
This story found itself reprinted in the Immortal Doctor Fate #1 (January, 1985), with a cover by Walt Simonson, along with a retold Dr. Fate origin from DC Special Series #10 (April, 1978) by Paul Levitz and Joe Staton and the solo Dr. Fate story from First Issue Special #9 (December, 1975) by Martin Pasko and Walt Simonson (where the ankh symbol was more fully incorporated into the Doctor Fate mythos).
This story was reprinted in Superman #252 (June, 1972) under a high-flying cover by Neal Adams, and this issue also features Golden Age Stories of Hawkman and Hawkgirl, the Spectre, Starman, Superman and more!
This tale was reprinted in Wanted, the World's Most Dangerous Villains #3 (November, 1972) under a Nick Cardy cover, and also had Golden Age Hawkman and Vigilante reprints, continuing the ties between Hawkman and Dr. Fate, as well as airing out great Golden Age stories!
This story was reprinted in Detective Comics #439 (February-March, 1974) under a cover by Neal Adams and Dick Giordano, with a Golden Age Hawkman reprint as well...and quite a few good Silver Age stories reprinted, as well as a new tale of Batman, and one of Archie Goodwin and Walt Simonson's Manhunter tales.
This tale is reprinted in Detective Comics #442 (August-September, 1974) with a Jim Aparo cover, and features Golden Ages tales of Black Canary, the Newsboy Legion and Batman, as well as Silver Age Hawkman and Elongated Man tales, and a new Batman story, and the next to last original chapter of Archie Goodwin and Walt Simonson's Manhunter.
This tale was reprinted twice on its own, once in Wanted, the World's Most Dangerous Villains #8 (June-July, 1973) with a Nick Cardy cover, and a Flash/Captain Cold battle, and reprinted again along with the rest of the contents of More Fun Comics #73 in the Millennium Edition: More Fun Comics #73 of January, 2001 along with the first appearances of Golden Age Green Arrow and Aquaman.
one of their charter members, and best of all, ALL of Dr. Fate's solo Golden Age adventures, with battles against Wotan, Ian Karkull, Mister Who, the Octopus, the Red Sage, the Clock and more from More Fun Comics #55 to #98 are available in the Golden Age Doctor Fate Archives #1 from 2007 (and his JSA tales in the All-Star Comics Archives). So, at least the early tales of Dr. Fate aren't that tough to dig up, but be careful picking it up, you might not be able to put it down! It would be magical if all DC's Golden Age was reprinted like this!
