The Flash #148

From November 1964, this Silver Age DC issue features a genuinely unnerving cover by Carmine Infantino and Murphy Anderson: a grinning villain in a blue-and-white patterned costume brandishes a boomerang overhead while standing atop a wooden bridge, taunting the Scarlet Speedster — who races toward him in full red-and-gold — with the threat of sending Flash into "an endless orbit around the Earth" via his so-called Boomerang-Bridge. The cover story, "The Day Flash Went Into Orbit!", promises the kind of imaginative, high-concept peril that made John Broome's scripts so entertaining in this era. If you enjoy Silver Age DC at its most inventively strange, this one's hard to pass up.
