Green Lantern Comic Book - 'Cosmic Enemy Number One!' (DC Comics)

This item is a vintage comic book titled 'Green Lantern,' prominently featuring the DC Comics logo in the upper left corner. The cover art depicts Green Lantern (Hal Jordan) in his classic green and black costume, appearing solemn and surrounded by a group of alien figures, some of whom are also dressed in green or hold power rings. A dramatic tagline reads, "...and for committing the worst of all crimes, GREEN LANTERN OF EARTH, you have been sentenced to be POWER-RINGED to DEATH!" another tagline reads, "COSMIC ENEMY NUMBER ONE!". The color palette is vibrant, dominated by shades of green, orange, and purple, characteristic of Silver Age comics. The comic appears to be protected within a clear plastic sleeve, suggesting an attempt at preservation. There is a price sticker on the upper right side, indicating '12¢' (original price) and an additional blue sticker with '20' written, likely a resale price or inventory mark. While the full condition is obscured by the sleeve and hands holding it, some minor edge wear or corner blunting might be present, typical for a comic of its age. The overall aesthetic points to a Silver Age publication, likely from the 1960s, given the 12-cent cover price and artistic style. The craftsmanship reflects standard comic book printing of that era, utilizing newsprint paper and a staple-bound format.
