Here's a real oddity from DC's Silver Age. In March, 1966, Flash #159 bore this cover:
The Fox story starts with Kid Flash and Barry Allen visiting the offices of Dr McNider (aka Dr Midnight), an Earth-Two physician. The doc is pleased to see the Earth-One heroes, but he wonders why Barry's not in his uniform. It turns out that the Flash is no more, because he feels underappreciated:
Armed with this knowledge, Flash and his junior partner travel to the future, defeat Frand Mattar, and return to 1966 just in time to prevent the bomb explosion from destroying the city. Flash gets banner headlines and the key to the city, showing that he is still Central City's hero.
Comments: Some tricky time paradox problems with this story. Wouldn't the future world know that the Flash had saved the city? And why would Frand Mattar send a bomb into the past in the first place (other than to provide Fox with a rationale for the cover)? Wouldn't a bomb about to affect a city in 3780 be more compelling to the people of that era?
However, the Fox effort is a masterpiece compared to the second story. Kanigher compares Flash's relationship with his uniform to that of a soldier and his gun.
Comments: Sweet jeebus, this is a wacky story! Kanigher's anthropomorphizing inanimate objects works in the war stories, but it is wildly out of place here. One thing that I do find interesting is that Kanigher gives Barry a better reason for quitting (and one that is more in line with what Lee would do with Spiderman a year later in ASM #50).
