BLUE BEETLE (vol. 3) #1 (June, 1964). Cover by Bill Fraccio and Frank McLaughlin.
"The Giant Mummy Who Was Not Dead!"
He just had a mild fever.
This book marks the origin and first appearance of the Charlton version of Dan Garrett Blue Beetle, who was much different from the original Blue Beetle from 1939.
Here, Dan Garrett is an archaeologist instead of a beat cop, and his last name is spelled with two Ts now. The original Blue Beetle wore a bulletproof (well, it was most of the time) chainmail-looking cellulose costume, and was granted "super energy" by Vitamin 2X, which gave him a varying degree of super-strength and stamina, depending on the demands of the story.
The new Blue Beetle was granted true superpowers - strength, flight, invulnerability, X-ray vision, etc. - courtesy of a mystical blue scarab he found in an abandoned Egyptian tomb. Which makes me wonder why the cover has him swinging on a rope since he could fly. Bill Fraccio was also the penciller of the story inside; did he forget he drew Blue Beetle flying several times?
Be that as it may, the new Blue Beetle didn't set the world on fire and, given the quality of the stories and art, that's not surprising. He only lasted ten issues before Charlton pulled the plug in 1965.
On a completely different note: the indicia on this issue states that this is Blue Beetle volume 2. While it's true that this was the second volume of the book published by Charlton (they published a four-issue series of Blue Beetle in the 1950s, consisting of reprinted and new stories), the true first volume of the book were the issues printed by Fox and Holyoke in the 1930s and 40s.
