Hal Jordan is the Green Lantern in continuity, and following the successful relaunch of the Flash in Showcase #4 (also on our Hot 100 list), DC brought back many other heroes of the Golden Age.
Other issues of Showcase on the Hot 100 include:
Showcase is a really tough run to put together in any condition. The renewed interest in various second-string DC Comic superheroes like Metal Men and Atom influences the price of the entire series.
This is a very expensive issue. If you can afford it, insist on VG or better: lower-grade copies don't present well, due to the cover being very vulnerable to wear.
