The Brave and the Bold #174

In "To Trap an Immortal," Batman teams with Green Lantern to unravel a deception among the Guardians of the Universe, as Sinestro—now disguised as one of them—has seized control of the Central Power Battery. With the help of The Old Timer, a once-immortal Maltusian now bound by mortality, the heroes must uncover the imposter before the power of the Green Lantern Corps is lost forever. Written by Gerry Conway and illustrated with sharp, dynamic precision by Jim Aparo—whose work defines the cover and interior—this 1981 DC classic blends cosmic intrigue with grounded detective work, all rendered in rich colors by Adrienne Roy and bold lettering by Aparo himself.
