Gil Kane returned to the Green Lantern character in the 1980s. Here are a few of my favorite covers from this period. There's a subtle theme here:
Green Lantern #166 features Hal Jordan in the foreground, with a green energy construct in the background that resembles himself! Self-love is the greatest love of all. The construct must have been drawn on a separate plate/overlay to achieve that color effect.
Green Lantern #171 is another iconic pose with Hal Jordan's face in the background. This time the background is an orange-red color.
Green Lantern #177 works the best, as Hal Jordan recharges in an all green background.
It's interesting to me that Gil Kane had such a long history with Green Lantern. He co-created the created in 1959, drew him exclusively for the first 10 years, and later returned for covers and specials in the 1980s and 90s. Nuff said.
