King

Few characters can claim a pedigree stretching from the very first issue of Flash Comics in 1940 all the way through to DC's landmark Who's Who: The Definitive Directory of the DC Universe — but King can, and that's a résumé worth tipping your hat to. Debuting in the Golden Age alongside luminaries like The Flash himself (Jay Garrick), The Whip, and The Vigilante, King was part of the remarkable inaugural wave of DC heroism that helped define an entire era of four-color adventure. With two of their scant four catalogued appearances recognized as key issues, King punches well above their weight in collector significance. A rare, fascinating corner of DC's Golden Age tapestry — exactly the kind of discovery that makes digging through the long boxes so rewarding.
